Tips on Reducing The Impact of Gold Mining And Processing

04/01/2019· The gold mining boom has caused destruction on the Amazon rainforest as artisanal and unlicensed gold miners tear down the environment to access hard to reach gold deposits underneath. These illegal gold miners use mercury to extract gold, leaching the toxic chemical into the air and water.
