gold mining process of gold extractions 」
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 steel balls.

Effects of Gold Mining on the Environment | .
Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This smallscale form of gold mining has little effect on the body of water, but the largescale practice of mining gold from ore can have tremendous negative effects on water quality. Gold typically sits in ore and sediment that contains toxins such as mercury. When ...

Cyanide Use in Gold Mining Earthworks
Cyanide''s efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;
