Removing the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravellike material then enters rotating drums filled with ...
· If the gold is still not back in its natural form, increase the strength of the acid solution and repeat the above steps. When dealing with small amounts of amalgam, usually the gold will be thoroughly cleaned off it after step 7. Sometimes when working with larger amounts of amalgam, it is necessary to do the steps a few times as described above, or to use a stronger acid solution.
· Enrichment or Concentration of Ore . An ore after mining from the ground contains many unwanted impurities like sand, rocky materials, etc. These unwanted impurities, including earthy materials, rocks, sandy materials, limestone, etc., are called gangue. The first step in metallurgy is to remove these unwanted impurities from the ore, to get a concentrated ore containing a much higher ...

Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank. Usually, kimberlite ore can be found in depths of at least 15 meters. When the diamondrich depth is reached, the raw ...

· The first step in kimberlite ore processing is crushing. This process reduces large runofmine lumps into smaller pieces, making them easier to handle, and releases or liberates the diamonds to be recovered in subsequent steps. Crushing is done in stages to "gently" free the diamonds from the kimberlite rock and produce a target size, usually less than 25 mm, for further processing. You ...
