Copper production process

Several different processes can be used for copper production. The old traditional process is based on roasting, smelting in reverbatory furnaces or electric furnaces for more complex ores, producing matte and converting for production of blister copper which is further refined to cathode copper

Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate (Optional partial roasting to obtain oxidized material or calcines) 2. Two-stage pyrometallurgical extraction 1. smelting concentrates to matte 2. converting matte by oxidation to crude (converter or blister) copper 3

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4

Global production of copper for 2020 was 20.6 million tons. While copper is produced around the globe, production is largely localized to select regions, specifically Latin America; in 2020, Latin America accounted for 41% of global copper mine production. Asia was the second largest producer at 16%, followed by Europe with 14%, North America

Copper Production Copper production is not an environmentally benign activity. From mining and milling through hydro- and pyrometallurgical processing to refin-ing, copper production can have significant ad-verse impacts on air quality, surface and ground-water quality, and the land (see figure 8-1 ). While these impacts can be severe when the
