The chemical, which has been used in mining for over 3,000 years, does not degrade in the environment. Research shows that forest canopies near small-scale gold mining sites can intercept and accumulate large volumes of atmospheric mercury pollution. This means mercury can build up and be passed along the food chain.

The purpose of a gold mill, at least a simple one, is to crush and grind rock fine enough to release small particles of gold. After liberating the gold from the rock or gangue, it is then run through a gravity separation step, which will concentrate most of the gold and wash off the lighter waste rock. Step 1.
