The Water Scalping-Classifying Tank was designed to meet federal and state aggregate specifications which are continually tightening. The function of the Water Scalping-Classifying Tank is to remove excess water and slimes, classify material by removal of excess in certain sizes, and retention of fines.
Slurry containing sand is introduced into the Tank at the feed end. As the slurry flows to the opposite end, solids settle to the bottom. Because of the difference in weight of different mesh sizes, material is automatically classified as it settles. Coarse material drops out first, near the feed end. Materials are progressively finer along the length of the Tank. At each setting station along the bottom of the Tank there are valves for discharging sand into the multi-cell collecting-blending flume for selective reblending. From there the sand is discharged into a Fine Material Washer; or Washers.
Gradation of the feed material in many pits may vary considerably, resulting in fluctuations in the amount of material passing through each valve. Originally the only method of controlling the specifications for the sand was with our Standard Series, requiring taking frequent samples of the product, and then manually readjusting the metering splitter gates. With modern technology, however, there are three control systems that will perform this task quite effectively.

Geology: TypeIntensely folded and faulted birimian flysch-type metasediments of the Paleoproterozoic age.
Mineralization Type: Narrow quartz veins within granite structures.
Production Scheduled: 2011
Estimated Mine Life: 10.2 years
The Central Ashanti gold mine is located approximately 57km south-west of Obuasi town and 195km north-west of Ghana’s capital Accra. Formerly known as Ayanfuri gold project, the mine has produced in excess of 300,000oz of gold between 1994 and 2001. It is owned by Central Ashanti Gold Limited, a wholly owned subsidiary of Perseus, which owns 650km² of tenements on the Ashanti gold belt.
The project is currently in the planning stage with a detailed feasibility study completed in July 2009. Production is scheduled to begin in 2011. The life of the mine is estimated to be approximately ten years.
Gold Mine Reserves
The mine contains an estimated 18.4Mt of proven reserves graded at 1.4g/t Au and 37.2 Mt of probable reserves graded at 1.1g/t Au. Measured and indicated resources total 29.9Mt graded at 2.1g/t Au. Inferred resources have been estimated to be 62.1Mt at 2.2g/t.
Gold Mine Geology
The deposit is hosted within the Man Shield of the Precambrian aged West African Craton. The deposit flanks the western end of the Ashanti greenstone belt along the Obuasi-Akropong gold corridor.
Intensely folded and faulted birimian flysch-type metasediments of the Paleoproterozoic age overlie the entire project area.
These sediments are metamorphosed to upper greenschist faces and include dacitic volcaniclastics, greywackes and argillaceous (phyllitic) sediments.
The sediments are intruded along multiple regional bodies by a number of small basin-type or Cape Coast-type granite structures.
The intrusions vary in size and shape from 200m to 400m long and 40 to 150m wide egg-shaped plugs, to longer and narrower sills and dykes that measure more than 2,000m in length and between 50m and 100m in width.
Regionally, the deposit hosts minor amounts of cherty and manganiferous exhalative sediments. Graphitic schists coincide with the main shear (thrust) zones. Parallel to partially parallel cleavage and bedding follow the regional trend of the 50° striking, steep to near vertical, southeast and north-west dipping Akropong structures.
Mineralisation
Gold mineralisation at the mine is found primarily within granite structures. Two or three generations of several, narrow quartz veins host the mineralisation. The quartz veins are associated with nearly 3% pyrite, minor arsenopyrite and lesser amounts of sphalerite, chalcopyrite, galena and rutile.
Gold observed at or near the margins of the veins, occurs as fine grains along the boundaries of sulphide grain or in sulphide fractures. Coarse visible gold is hosted within the quartz. Mineralisation also occurs in shear zones that host the classic Ashanti-style sediments.

Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls).
Grinding clinker requires a lot of energy. How easy a particular clinker is to grind (“grindability”) is difficult to predict, but rapid cooling of the clinker is thought to improve grindability due to the presence of microcracks in alite and to the finer crystal size of the flux phases. It is frequently observed that belite crystals, which have a characteristic round shape, tend to separate and form single crystal grains during grinding.
As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO4.2H2O). Natural anhydrite may also be added to discourage lumpiness of the gypsum due to its water content.
Since the clinker gets hot in the mill due to the heat generated by grinding, gypsum can be partly dehydrated. It then forms hemihydrate, or plaster of Paris – 2CaSO4.H2O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO4). This has a similar solubility in water to hemihydrate, which in turn has a higher solubility than either gypsum or natural anhydrite.
Cement mills need to be cooled to limit the temperature rise of the cement. This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill.
The relative proportions and different solubilities of these various types of calcium sulfate are of importance in controlling the rate the rate of C3A hydration and consequently of cement set retardation. Problems associated with setting and strength characteristics of concrete can often be traced to changes in the quantity of gypsum and hemihydrate, or with variations in cooling rate of the clinker in the kiln and subsequent changes in the proportions or size of the C3A crystals.
For set regulation, the most important feature of aluminate is not necessarily the absolute amount present, but the amount of surface which is available to water for reaction. This will be governed by many factors, such as the surface area of the cement, the grinding characteristics of the different phases and also the size of the aluminate crystals. Over-large crystals can lead to erratic setting characteristics.

If you happen to be a geologist, the raw materials quarry is probably the most interesting part of a cement works, maybe unless you view the clinkering process as igneous rocks in the making.
The most common raw rock types used in cement production are:- Limestone (supplies the bulk of the lime)
- Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide)
- Other supplementary materials such as sand, pulverised fuel ash (PFA), or ironstone to achieve the
Desired bulk compositionQuarry management is an art. Most quarries will probably have “good material” from which cement can easily be made. They may also have some material that is not as good; this might be harder to grind, or be of less convenient composition.
If the ‘good stuff’ is all used up first, it may be difficult to make cement out of what is left. Careful selection on a day-to-day basis is needed to make the best use of all the materials available.
Raw materials are extracted from the quarry, then crushed and ground as necessary to provide a fine material for blending. Most of the material is usually ground finer than 90 microns – the fineness is often expressed in terms of the percentage retained on a 90 micron sieve.
Once the the raw materials are ground fine enough, they are blended in the proportions required to produce clinker of the desired composition.
The blended raw materials are stored in a silo before being fed into the kiln. The silo stores several days’ supply of material to provide a buffer against any glitches in the supply of raw material from the quarry.
Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.
Supplementary materials are used to adjust the composition of the raw meal but cost and availability are likely to determine the extent to which they are used. Transport costs in particular become significant in view of the large quantities of materials used in making cement.

By the process of hydration (reaction with water) Portland cement mixed with sand gravel and water produces the synthetic rock we call concrete. Concrete is as essential a part of the modern world as are electricity or computers.
Other pages on this web site describe how PC is made and what is in it. Here, we will discuss what happens when it is mixed with water.
Clinker is anhydrous (without water) having come from a hot kiln. Cement powder is also anhydrous if we ignore the small amount of water in any gypsum added at the clinker grinding stage.
The reaction with water is termed “hydration”. This involves many different reactions, often occurring at the same time. As the reactions proceed, the products of the hydration process gradually bond together the individual sand and gravel particles, and other components of the concrete, to form a solid mass.
The hydration process: reactions
In the anhydrous state, four main types of minerals are normally present: alite, belite, aluminate (C3A) and a ferrite phase (C4AF). For more information on the composition of clinker, see the clinker pages. Also present are small amounts of clinker sulfate (sulfates of sodium, potassium and calcium) and also gypsum, which was added when the clinker was ground up to produce the familiar grey powder.
When water is added, the reactions which occur are mostly exothermic, that is, the reactions generate heat. We can get an indication of the rate at which the minerals are reacting by monitoring the rate at which heat is evolved using a technique called conduction calorimetry. An illustrative example of the heat evolution curve produced is shown below.
Three principal reactions occur:
Almost immediately on adding water some of the clinker sulphates and gypsum dissolve producing an alkaline, sulfate-rich, solution.
Soon after mixing, the (C3A) phase (the most reactive of the four main clinker minerals) reacts with the water to form an aluminate-rich gel (Stage I on the heat evolution curve above). The gel reacts with sulfate in solution to form small rod-like crystals of ettringite. (C3A) reaction is with water is strongly exothermic but does not last long, typically only a few minutes, and is followed by a period of a few hours of relatively low heat evolution. This is called the dormant, or induction period (Stage II).
The first part of the dormant period, up to perhaps half-way through, corresponds to when concrete can be placed. As the dormant period progresses, the paste becomes too stiff to be workable.
At the end of the dormant period, the alite and belite in the cement start to react, with the formation of calcium silicate hydrate and calcium hydroxide. This corresponds to the main period of hydration (Stage III), during which time concrete strengths increase. The individual grains react from the surface inwards, and the anhydrous particles become smaller. (C3A) hydration also continues, as fresh crystals become accessible to water.
The period of maximum heat evolution occurs typically between about 10 and 20 hours after mixing and then gradually tails off. In a mix containing PC only, most of the strength gain has occurred within about a month. Where PC has been partly-replaced by other materials, such as fly ash, strength growth may occur more slowly and continue for several months or even a year.
Ferrite reaction also starts quickly as water is added, but then slows down, probably because a layer of iron hydroxide gel forms, coating the ferrite and acting as a barrier, preventing further reaction.  
Hydration products
The products of the reaction between cement and water are termed “hydration products.” In concrete (or mortar or other cementitious materials) there are typically four main types:
Calcium silicate hydrate: this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists’ notation, to “C-S-H,” the dashes indicating that no strict ratio of SiO2 to CaO is inferred. The Si/Ca ratio is somewhat variable but typically approximately 0.45-0.50 in hydrated Portland cement but up to perhaps about 0.6 if slag or fly ash or microsilica is present, depending on the proportions.
Calcium hydroxide – Ca(OH)2: often abbreviated to ‘CH.’ CH is formed mainly from alite hydration. Alite has a Ca:Si ratio of 3:1 and C-S-H has a Ca/Si ratio of approximately 2:1, so excess lime is available to produce CH.
AFm and AFt phases: these are two groups of minerals that occur in cement, and elsewhere. One of the most common AFm phases in hydrated cement is monosulfate. By far the most common AFt phase in hydrated cement is ettringite. The general definitions of these phases are somewhat technical, but for example, ettringite is an AFt phase because it contains three (t-tri) molecules of anhydrite when written as C3A.3CaSO4.32H2O and monosulfate is an AFm phase because it contains one (m-mono) molecule of anhydrite when written as C3A.CaSO4.12H2O.
The most common AFt and AFm phases in hydrated cement are:
Ettringite: ettringite is present as rod-like crystals in the early stages of reaction or sometimes as massive growths filling pores or cracks in mature concrete or mortar. The chemical formula for ettringite is [Ca3Al(OH)6.12H2O]2.2H2O] or, mixing notations, C3A.3CaSO4.32H2O.
Monosulfate: monosulfate tends to occur in the later stages of hydration, a day or two after mixing. The chemical formula for monosulfate is C3A.CaSO4.12H2O. Note that both ettringite and monosulfate are compounds of C3A, CaSO4 (anhydrite) and water, in different proportions.
Monocarbonate: the presence of fine limestone, whether interground with the cement or present as fine limestone aggregate, is likely to produce monocarbonate (C3A.CaCO3.11H2O) as some of the limestone reacts with the cement pore fluid. Other AFm phases that may be present are hemicarbonate, hydroxy-AFm and Friedel’s salt.
Some important points to note about AFm and AFt phases are that:

They contain a lot of water, especially AFt – principally ettringite in the context of cement.
AFm contains a higher ratio of aluminium/calcium compared with AFt.
The aluminium can be partly-replaced by iron in both AFm and AFt phases.
The sulfate ion in monosulfate AFm phase can be replaced by other anions; a one-for-one substitution if the anion is doubly-charged (eg: carbonate, CO22-) or one-for-two if the substituent anion is singly-charged (eg: hydroxyl, OH- or chloride, Cl-).
The sulfate in ettringite can be replaced by carbonate or, probably, partly replaced by two hydroxyl ions, although in practice neither of these is often observed.

In a concrete made from cement containing just clinker and gypsum, ettringite forms early on in the hydration process, but gradually replaced by monosulfate. This is because the ratio of available alumina to sulfate increases with continued cement hydration; on first contact with water, most of the sulfate is readily available to dissolve, but much of the C3A is contained inside cement grains with no initial access to water. Continued hydration gradually releases alumina and the proportion of ettringite decreases as that of monosulfate increases.
If there is eventually more alumina than sulfate available, all the sulfate will be as monosulfate, with the additional alumina present as hydroxyl-substituted AFm phase (hydroxy-AFm). If there is a small excess of sulfate, the cement paste will contain a mixture of monosulfate and ettringite. With increasing available sulfate, there will be more ettringite and less monosulfate, and at even higher levels of sulfate there will be ettringite and gypsum.
If fine limestone is present, carbonate ions become available as some of the limestone reacts. The carbonate displaces sulfate or hydroxyl in AFm; the proportion of monosulfate or hydroxy-AFm therefore decreases as the proportion of monocarbonate increases. The displaced sulfate typically combines with remaining monosulfate to form ettringite, but if any hydroxy-AFm is present, the sulfate will displace the hydroxyl ions to form more monosulfate. The key here is the balance between available alumina on the one hand, and carbonate and sulfate on the other.
Hydrogarnet: hydrogarnet forms mainly as the result of ferrite or C3A hydration. Hydrogarnets have a range of compositions, of which C3AH6 is the most common phase forming from normal cement hydration and then only in small amounts. A wider range of hydrogarnet compositions can be found in autoclaved cement products.

Ball mill types
Ball mills are used for grinding things down or for mixing things up. They grind ores down to powders before they are chemically processed, they grind grains down to flours for baking and they mix up paints so they are smooth enough to apply. All ball mills consist of rotating cylinders that contain hard (usually metallic) balls that do the grinding. There are three types of ball mills: horizontal, vertical and industrial.
Horizontal Ball Mills
crusher.com” />
Ball Mills

Horizontal ball mills are the most common type. The basic design is the same but the details can vary slightly. A drum, which is usually detachable, has a door that can be used to load in the material to be processed. Sometimes — like for paint mixers — there will be a crusher.com”>screen that keeps the metal balls in place. When the substance to be processed (and the balls) are in the drum, the door is closed and the drum is reinstalled — horizontally — on the mill where it is rotated until the job is done. Some ball mills have a timer and some have a window where the processed material can be viewed.
Vertical Ball Mills
Small vertical ball mills are about the size of a blender and are intended for laboratory or shop use. They are small enough to fit on a lab table or workbench and only big enough to process the small quantities need for desktop applications — they are not intended for commercial or industrial use. These ball mills are often called planetary ball mills. The rotating drums are not usually detachable — the material is poured into the top and the cap is replaced, like a kitchen blender. Like all ball mills, the speed and ball size have an effect on how the vertical crusher.com”>ball mill works. Vertical ball mills often come with a variety of ball sizes (and have variable speed settings) for more efficient processing.
Industrial Ball Mills
Industrial ball mills are much larger than the other types of ball mills. They vary in size from approximately the size of a refrigerator to approximately the size of a bus. They are always horizontal. What distinguishes the industrial ball mill (besides its large size) is that they have multiple chambers and have a forced-air system constantly moving material through the rotating drum. The different chambers are separated by screens of progressively smaller mesh. The chambers contain balls of progressively smaller size. The size of the balls and the screen mesh keeps the balls in their own chamber. Material is forced from one chamber to the next as it is ground small enough to fit through the mesh screens.

Introduction of Zimbabwe Ore Dressing Process
Ore dressing approach will be the preparatory operate of smelting. Following mining of ores, over all, metallic elements like iron, copper, aluminium, manganese really should be separated from ores, which makes planning for the following smelting process. Ore dressing procedure contains crushing, grinding and separation approach. Amongst them, crushing method is divided into primary crushing, secondary crushing and tertiary crushing. You will discover different separation techniques: magnetic separation, gravity focus, flotation, etc. The goal of ore dressing procedure is usually to improve the quality of ores. #
Zimbabwe Ore Dressing Methods
Gravity concentration: Distinct ores have various precipitation velocity in medium because of their distinctive densities, so they're separated from each other.
Magnetic separation: This approach tends to make use of the variety of ores’ magnetism. In uneven magnetic field, magnetic minerals attract the pole in magnetic separator, even though non-magnetic minerals repel. #
Flotation: This system makes utilization of distinct hydrophilicities of minerals’ surface. Strongly hydrophobic minerals are floated to pulp surface with foams, when hydrophilic minerals stay in ore pulp. In this way different minerals might be separated.
Zimbabwe Ore Solutions Produced by way of Beneficiation
Products of ore dressing method: focus, middling, tailing.
Concentrate may be the item created immediately after ore dressing method, which contains rather high content material of helpful minerals. #
Middling is intermediate item produced through ore dressing approach, which will need further treatment.
Tailing would be the waste left immediately after ore dressing procedure.

Dimension Stone

The Stone Tiles, Stone Slabs is one of dimensional stones. Dimensional stones are the stones that are cut and shaped with specific dimensions. These stones look really beautiful and have a fairly good market not only in India but there is a considerable demand abroad also. Dimensional stones were introduced with the introduction of imported sawing, polishing, tiling and cutting machines. Dimensional stones can be in the form of tiles, slabs, circle or steps. Each of the stone has distinctive characteristics and functions in our daily life. Dimensional Stone is often used for architectural accents such as quoins, jack arches, window sills, keys, trim, coping, hearths, and treads.
