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. The flash smelting process for sulphide concentrates was developed by the Finnish mining company, Outokumpu Oy, from 1948 ...
AN INTRODUCTION TO OUTOTEC FLASH SMELTING With flexibility, low energy consumption, high sulfur capture, and excellent economy of scale, Outotec Flash Smelting technology is the world''s leading method for copper and nickel smelting. More than half of the world''s primary copper and nickel is produced using Outotec''s proprietary process.

In the 1940s, the Finnish state''s copper company, Outokumpu, had a problem: it needed electricity to refine metal, but there was a shortage of electricity in Finland. A solution was found in a proposal to manufacture copper without using external energy. The flash smelting method uses the sulfur present in the ore. The invention marked the ...

Originally Outotec''s former parent company Outokumpu developed the Flash Smelting technology for its own use. In 1949 Outokumpu introduced autogenous Flash Smelting of copper concentrates at its facility in Harjavalta, Finland. The technology has been continuously developed to meet industry needs.
One of several cuttingedge technologies developed at the ORC is Outotec Flash Smelting, which is still one of the world''s most commonly used processes to produce primary copper and nickel. This innovation was developed at the ORC at the end of 1940s.
1999 marked the 50th anniversary of the Outokumpu flashsmelting process. Originating during the postWorld War II energy crisis, flash smelting is a highintensity process developed to attain everincreasing throughputs and intensities. Many innovations and continuous development ensued during the next 50 years before today''s stateoftheart coppermaking process chain and environmental ...

Copper Age. Copper occurs naturally as native metallic copper and was known to some of the oldest civilizations on record. The history of copper use dates to 9000 BC in the Middle East; a copper pendant was found in northern Iraq that dates to 8700 BC. Evidence suggests that gold and meteoric iron (but not iron smelting) were the only metals used by humans before copper.
