Although mining exposes all of the contaminants, refining isolates and concentrates waste, in order to isolate and concentrate the desired final product. Refining processes also often use harsh acids and bases to separate the desired metals from the wastes, which can harm the environment by themselves when they change soil and water chemistry.

When companies break up materials during mining, the dust can release a variety of heavy metals commonly associated with health problems. As dust, these minerals (such as the asbestos-like mineral riebeckite) can be absorbed into lung tissue, causing problems like pneumoconiosis and silicosis, commonly known as "Black Lung" (Paul & Campbell, 2011).
