What are the two primary copper minerals?

There are two main copper ore types of interest, copper oxide ores and copper sulfide ores. Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production.

What is a secondary copper mineral?

They generally result from the breakdown of common primary copper minerals such. as chalcopyrite, bornite, chalcocite, and covellite or alternatively via the dissolution.

What is the primary ore of copper?

mineral chalcopyrite
Copper – Most copper ore bodies are mined from minerals created by weathering of the primary copper ore mineral chalcopyrite. Minerals in the enriched zone include chalcocite, bornite, djurleite. Minerals in the oxidized zones include malachite, azurite, chyrsocolla, cuprite, tenorite, native copper and brochantite.

What is the difference between primary and secondary metals?

Primary refers to the production of metal from ore. Secondary refers to production of alloys from ingots and to recovery of metal from scrap and salvage. The primary metals industry includes both ferrous and nonferrous operations.

Which mineral is a source of copper?

Copper is found in many minerals which occur in deposits large enough to mine. These include: azurite, malachite, chalcocite, acantite, chalcopyrite and bornite. Most copper comes from chalcopyrite. The world’s leading producer of copper is Chile, followed by the U.S and Peru.

What are secondary ores?

1.4 Primary and Secondary Ores Secondary ore minerals are those deposited during subsequent weathering at or near the surface. The effect of weathering is to leach many metals from the ore to leave a leached capping or gossan. These metals may then enrich the underlying ore in a process known as secondary enrichment.
