Acid Mine Drainage Flow-Through Experiments Examining

through mining exposes the coal and pyrite to air, initiating the oxidation reaction. These reactions mainly occur in two places the exposed coal seams and in waste piles. The pyrite in the coal is not useful and so the pyrite is discarded into waste piles. Pyrite, discarded coal, and overburden rock and soil sit in waste piles and oxidation occurs.

Copper Mining and Processing Everything you Need to

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then undergoes several refining
