Enhancing the flotation recovery of copper minerals in

Jan 01, 2020· The milling response of the different slags showed that the reverberatory slag mills much more easily in comparison to the TSL slag and the converter slag. The response also showed that there is an inverse relationship between the ease of milling and the copper mineral content of the slag

Effect of Cooling Rate and Slag Modification on the Copper

copper sulfide particles was promoted, and thereby the parti-cles could be better collected in the subsequent flotation to reduce copper losses in the waste slag. In addition to testing the cooling time and controlling the cooling rate, some researchers have even considered using slag modification to increase copper recovery. Wang [18]

Recovery of cobalt, nickel, and copper from slags, using

Nickel-copper converter slag 'A'- 100 kVA and 200 kVA. Using converter slag from a nickel-copper plant, tests were carried out, in 1990, on a 100 kVA furnace (operated at 30 kW) and on a 200 kVA furnace (operated at 85 kW), at low additions of reductant (in order to minimize the reduction of iron).

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
