Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity refined copper.
Flash smelting is a pyrometallurgical process for smelting metal sulphide concentrates. It is used primarily for copper sulphide concentrates, but it is also used to a significant extent for nickel sulphide concentrates.

This process is only one truly continuous process established in a commercial scale all over the world, which has a superior technology for copper smelting and converting. It is recognized as the most cost effective and environmental friendly process, and yielding anode copper directly from copper concentrate
For example, if you ship a lead-copper concentrate to a lead smelter, you will receive about 30 cents a pound less for the copper, while if this same lead-copper concentrate is shipped to a typical copper plant, you will be paid for only half the lead and will get about 40 cents a pound less for that lead.
Dec 06, 2017· When smelters and miners can't come to an agreement, that should give even the most bullish investors reason to pause. The typical split is around 80 percent concentrates to 20 percent refined copper -- although some miners, such as Lundin Mining Corp., produce concentrates exclusively.

Copper has a vast range of household and industrial uses. Its superior electrical conductivity makes it ideal for electronics, such as wiring and computer connections; and its ability to heat up and cool down quickly makes it ideal for heat exchange applications such as air conditioners.
Losses in copper smelting are low with loss of copper being between 4.5% to 6%; silver 3 to 5% and gold 1 to 2%. Most copper concentrates smelted are very fine which result in high dust losses during roasting and smelting operations.
