Copper Ore Concentrate Recovery

Recovery of Copper from Copper Sulfide Concentrate by

metallurgical methods has been used for the recovery of copper from a copper sulfide concentrate. The reactions investigated show an enhanced recovery of copper from its concentrate into a leachate which is almost devoid of iron. Suitable roasting temperatures, roasting time and proper amount of addition have been explored in this a study. 2

Copper extraction Wikipedia

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite
