Copper Mining and Processing: Processing Copper Ores

A. Processing of Oxide OreB. Processing of Sulfide OreC. Recycling Copper

Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating chemical solutions to leach out meta...

2021年9月16日 After mining, copper is produced by one of two process routes: pyrometallurgical or hydrometallurgical. Within the pyrometallurgical route, the mined ore is crushed and milled, followed by a concentration step using flotation. The obtained copper concentrates contain on average 30 percent copper, but grades can range from 20 40

Mining And Refining: Copper, The Metal That Built

2022年1月10日 To extract the copper from the concentrate, a flash smelting process is used. Concentrate is sprayed into a reaction column in a flash furnace along with heated, oxygen-enriched air.

Copper Processing Multotec

The copper concentrate is first placed in the smelting furnace to be heated up to 1260 °C and converted into molten liquid. Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Multotec is committed to your copper extraction process, consistently
