What is Copper Concentrate? - Arij Trading

The flotation is made selective by using reagents, which make the Cu-sulfide minerals water-repellent (hydrophobic) while leaving the other minerals wetted (hydrophilic). Typical Cu sulfide recoveries to concentrate are 85–90%. Modern concentrators are automatically controlled to give maximum Cu recovery, maximum % Cut in the concentrate, and maximum ore throughput rate at minimum cost ...

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, sphalerite or galena. Chalcocite concentrates ...
