The beneficiation methods of oxidized copper ore mainly include gravity separatio, magnetic separation (see details on copper ore processing plant), flotation and chemical beneficiation. Azurite: a kind of copper oxide ore
Copper is most commonly present in the earth's crust as copper-iron-sulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS2), bornite (Cu5FeS4) and chalcocite (Cu2S).
Copper slag, a waste solid produced in the copper smelting process, is a high-quality secondary resource with huge output. The recycling and utilization of copper slag is of great interest because it avoids the loss of valuable metals and the threat of harmful metals, and saves a lot of natural resources and energy. This paper firstly reviews the main methods for …

1. Introduction. The Nussir copper deposit is a sedimentary-hosted copper deposit located in the Kvalsund Municipality, Finnmark County, Norway, stretching from Repparfjorden in the east to the western part of the Nussir area. Moen et al. (Citation 2014) confirmed the presence of chalcopyrite, chalcocite, bornite, covellite and digenite as the major copper minerals with …
About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. …
