gold extraction mining related machinery

Gold and science are very much related. Without science we wouldn't know what chemicals to use to extract the gold from the rocks, and we wouldn't have any of the machinery needed to mine gold. We also need science to test the water quality and to clean the used water. Gold extraction and processing is a complex process which has many impacts

Gold: History of Use, Mining, Prospecting, Assay

Gold particles in stream deposits are often concentrated on or near bedrock, because they move downward during high-water periods when the entire bed load of sand, gravel, and boulders is agitated and is moving downstream.
