 · Both ore types can be economic, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for ~50% of copper production. Sulfide copper ores are the most profitable ores because they have high copper content, and refiners easily separate copper from the gangue.

From Ore to Finished Product

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

CHALCOCITE (Copper Sulfide)

Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur. It is not however the primary ore of copper due to its scarcity.
