We specialize in the design, detailed engineering, supply, erection and commissioning of mineral beneficiation plants for the following: Lead-Zinc-Copper- Pyrite Ores, Rock Phosphate Ore, Fluorspar Ores, Tin Tungsten Ores, and so on. We have already created a low-grade rock phosphate beneficiation plant and commissioned it in India. This can be the very first plant set up inside the private sector, which has been working successfully.
We have a team of authorities in evaluation of ore characteristics and development of standard engineering for setting up beneficiation plants for the metallic and non-metallic ores.
Phosphoric Acid Plant
The Sulfuric Acid, Rock phosphate Mineral Powder and water are mixed in a agitated approach vessel connected with scrubber program. The above slurry solution is filtered as well as the filterate is Collected in an additional agitated process vessel as Crude Phosphoric Acid for additional processing. The solid part is Gypsum, that is thoroughly washed with water to produce it totally free from Crude Phosphoric Acid. The wash water recycled water containing phosphoric Acid is recycled in subsequent batch with Rock phosphate and Sulphuric Acid. Throughout this step the impurities of Rock Phosphate Mineral [such as Florspar CaF2, CaCo3 Lime stone] are reacted with Sulphuric Acid. The CaF2 forms HF with sulphuric Acid. dolomite crusher
The HF is reacted with Silica to types SiF4 is extremely soluble in water to form H2SiF6 and silica inside the Scrubber in addition to inside the agitated Procedure vessel. This Acid is concentrated and the concern condensate in neutralised with Ca(OH)2 & insoluble precipitate is mixed with hyproduct Gypsum. The Crude Phosphoruc Acid contains further some H2SiF6 The H2SiF6 [Hydro Silicic acid or Hexa Fluoro Silicaste] is mixed with Lime stone Powder to form insoluble Florspar (CaF2), that is soluble only in strong concentrate acid. This really is also filtered with partial precipitate of Calcium Phosphate (Tri) this insoluble is recycled with Acid recovery of P2O5 in Adulation method with Rock Phosphate. After filtering above Slurry Solution, the filterate is Purified Phosphoric Acid. basalt crusher
Synthetic Gypsum Plant
Lime Stone is ground to min. 65% -300 mesh and is stored inside the over head bin. Automatic weigh scale is installed to control the feed into Mixer. Sulphuric acid (60-98%) and water is pumped to Mixer. Sulphuric Acid and water is metered with an automatic control meter which maintains acid-Lime powder-water ratio at the pre-determined setting. The discharge of Mixer goes into DEN (a specially created equipment ). In DEN material cured slowly under the suction for collecting of gas generate within the Mixer and DEN.
The Synthetic Gypsum material is transferred from DEN to storage piles, where further curing takes place. It contains about 12% moisture and for the duration of this maturing stage the moisture content reduces. It is dug out with a Grab Bucket E.O.T. crane for additional processing or dispatched in bulk or packed form.
