Impacts of copper mining on people and nature | Danwatch

The mining industry uses sulphuric acid in the extraction and treatment of copper. The extraction processes are called heap and situ leaching; during these processes, particles react with each other to create acidic mists that not only harm people''s skin, eyes and lungs, but also destroy crops, deteriorate the quality of the land, and damage nearby buildings.
