Water Pollution. Gold mining also has the potential to contaminate any nearby water supplies. Acid washed out of mines frequently finds its way into the water table, altering the pH of nearby streams and rivers and threatening the survival of wildlife. If a tailings reservoir bursts, it can result in a toxic mudslide that can block the flow of ...

Suppose you wish to separate a mixture of fine particles of gold and sand, neither of which is soluble in water. If you add liquid mercury to the mixture, the sand will float to the top of the mixture while the gold will dissolve. The sand can then be skimmed from the surface. You can recover the gold by heating the solution toevaporate the liquid
