First Quantum (FM), based in Vancouver, Canada, produced 520,690 metric tonnes of copper in 2017. The company is a well-established and growing metals and mining company producing mainly copper, gold, nickel, and zinc. The company plans to greatly increase its copper production in coming years.
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.
Copper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

TENORM: Copper Mining and Production Wastes Within the United States, mining and production of copper are primarily located in the West, specifically Arizona, New Mexico, Utah, Nevada and Montana. According to the United States Geological Survey (USGS), production in these states and Michigan account for more than 99% of domestic copper production.
for copper production. The traditional process is based on roasting, smelting in reverbatory fur-naces (or electric furnaces for more complex ores), producing matte (copper-iron sulfide), and con-verting for production of blister copper, which is further refined to cathode copper. This route for production of cathode copper requires large

Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2, also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an
What is more, the company processes ore to obtain concentrate and metallic copper in the form of wire rod, Cu-OFE and Cu-Ag wire, round billets and granules. Most of KGHM's production is sold on the basis of long-term contracts (typically annual contracts or longer), with the balance sold under short-term or "spot"agreements. Cathodes
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.
