Copper: An Ancient Metal
Copper, lead, cadmium and arsenic contaminate the huge pit, which is recharged with water every day from an aquifer below—making the toxic lake nearly impossible to clean up. Sulfur, a mineral that is commonly a component of copper ore, reacts with air and water, producing sulfuric acid, which fills the pit.

Copper Statistics and Information
Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.
