Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.
Sulphide copper ores are normally concentrated by flotation while the oxide ores undergo hydrometallurgical treatments. The mixed sulphide-oxide copper ores may be processed by combined methods such as flotation followed by leaching and precipitation of the oxidized portion, or vice-versa.
Dec 26, 2017· Copper processing is a complicated process that begins with mining of the ore less The most common types of ore, copper oxide and copper sulfide, undergo two To remove the ore, boring machinery is used to drill holes into the hard rock, and The slurry is a mix of valuable copper ore minerals and worthless rock,
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.
The copper concentrate processing equipment needed in copper ore processing is complex because of the different property of copper concentrate. However, the main copper processing equipment for copper ore is same as other mining processing steps, including crushing, grinding, flotation separating and dewatering.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.
