A stamp mill was obviously a mechanical crusher, noisy, heavy and somewhat awkward to use. The stamps were heavy metal and rock weights that were lifted and dropped around the ore by the crankshaft. The crushed ore would then be further refined, usually with a mercury or cyanide process.

Rod Mill

The task explained:
The miner would bring the ore towards mill and load it in the ore car. The heavy ore car can be mentioned for the mill using a tram-track by way of the aid on the winch.

As soon as the ore was presents itself the mill, the car can be emptied through to a screen termed as 'grizzly.' The 'grizzly' must have been a metal grate with separators a couple of inches apart (regarding the distance from the claws on the paw on the grizzly bear). Smaller material would fall with the screen and on the ore chute while larger material would slide through the 'grizzly' in to the crusher. The more expensive fecal material ore passing into your crusher would remain until these were pounded in a workable size (less than 2 inches) then fall under the ore chute.

The ore, now concerning the measurements a training course gravel would, slide to the rock plates below the stamp battery where water would be poured on. Battery usually was comprised of teams of 5 stamps (5 stamp, 10 stamp, 20 stamp mills, etc). The stamps can be lifted in sequence using a powered cam after which dropped using gravity to to pulverize the ore in a fine, sandy slurry. gold processing equipment

The slurry can be spread evenly on the recovery table. The recovery table became a copper-sheeted table that was coated with mercury prior to the processing run. The gold within the sand would adhere to the mercury whilst the sand would pass to the site the next step in the process, the concentration table.

The concentration table was obviously a table with runners that would shake or vibrate, slowing the heavier material containing the gold with a stop while letting the worthless tailings pass to the conveyor for being transported away. The crushed sand in the table will be loaded into the stamp mill, pulverized further just as soon as again slurried over the mercury coated recovery table. stone processing plant

In the event the mercury for the recovery table was full, or ore run was complete, the gold and mercury could be scrapped over table and separated. Separation could be accomplished by straining the amalgam mixture by way of a chamois. Further separation might be performed by a retort process. The retort would heat the mercury removing it from your gold as vapor and condensing it . The gold was now in amalgam form, ready for extra refinement processes for example smelting into bullion.

Jaw crushers were designed to look at big rocks and partially crush them into a far more workable size. A considerable pair of jaws would close and open crushing the ore similar to a nut cracker crushing a nut instead of just cracking it.
