A typical concentrate of chalcocite can grade between 37% and 40% copper in sulfide, making them relatively cheap to smelt compared to chalcopyrite concentrates. Some supergene sulfide deposits can be leached using a bacterial oxidation heap leach process to oxidize the sulfides to sulfuric acid, which also allows for simultaneous leaching with

An Ore is a naturally occurring material in shape of rock which contains a metal compound. When extracted from the mine ore is typically crushed, ground and run through a beneficiation process to produce enriched ore called Concentrate .One of the most widely used ore beneficiation process is called froth flotation where the minerals are separated from each other.

Copper Ore And Copper Concentrate by Fastlane Production

Product Description Copper Ore /copper concentrate /Raw Copper Ore/Copper Ore Lumps Currently, the most common source of copper ore is the mineral chalcopyrite (CuFeS2), which accounts for about 50% of copper production. The focus of this article is on the process of copper extraction from chalcopyrite ore into pure metal. Processes for other minerals are mentioned.

Influence of seawater and discard brine on the dissolution

This paper reports a study on the dissolution kinetics of finely ground copper oxide ore, chalcopyrite ore, and chalcopyrite concentrate leached in shake flasks, agitated reactors and columns using seawater and discard brine as the leaching solution. The type of chloride solution did not affect the dissolution of the copper oxide mineral.

This result agrees with previous reports which found that silver enhanced chalcopyrite bioleaching at moderate temperatures. The GEOCOAT process can be used to leach high yields of copper from chalcopyrite concentrates over a wide range of copper grades. In addition, substantial copper recoveries may be achieved in as little as 90 days.
