whats are the factors that pollute around gold mines

Reducing Mercury Pollution from Artisanal and Small-Scale Gold Mining

Mercury has long been used in artisanal and small-scale gold mining (ASGM) to extract gold from ore sediment and rock deposits. ASGM accounts for more than a third (38%) of all anthropogenic mercury emissions to the atmosphere, with most ASGM sector-related mercury emissions coming from the burning of mercury-gold amalgam.

How does mine drainage occur? | U.S. Geological Survey

Mine drainage is surface water or groundwater that drains from an active or abandoned mine. In some cases, pyrite (an iron sulfide mineral) is exposed and reacts with air and water to form sulfuric acid and dissolved iron. Some or all of this iron can precipitate to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage.
