Sulfide Mining Overview Save Our Sky Blue Waters

Mines are either open pit mines or underground operations. Open pit mines are most commonly used, 83 percent of copper mines in the US are open pit.14 This method is used because a greater amount of ore can be processed and the processes offer more safety and access for mine workers. 15 In open pit operations, the fist step is the removal of
