Innovations: How Hydrometallurgy and the SX/EW Process ,
A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here Conventional Copper Extraction Conventionally, copper is recovered by a pyrometallurgical process known as smelting In this process copper ore is mined, crushed, ground, concentrated, smelted and refined
Copper Mining and Processing: Processing of Copper Ores ,
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different .
In the flotation process, the finely ground ore, mixed with water and special reagents, is agitated by mechanical and pneumatic devic These produce air bubbles in the ore-water mixture, or slurry The reagents provide an attraction between the surface of the copper minerals and the air bubbl
