In 1946, the Finnish company Outokumpu (now Outotec) began to develop flash smelting technology. In 1949, due to a shortage of electricity, the company's Harjavalta smelter replaced the electric furnace with the flash furnace for copper smelting, marking the successful industrial application of the Outotec flash smelting technology. ...

The technology was operated on industrial scale for the first time at the Outokumpu Harjavalta copper smelter in Finland in 1949. Since then Flash Smelting technology, now …

The Flash Smelting technique was developed initially for the copper sulphide concentrates but adopted shortly thereafter for nickel, iron and lead sulphide concentrates [4-5] which brought additional dimensions to the process chemistry. Altogether 58 flash smelting furnaces have been built so far, including the

In Copper Flash Smelting, flue dust can cause severe problems in the gas handling system, which typically consists of a heat recovery boiler and electrostatic precipitator. If the process is not operated properly, the flue dust may form accretions on the boiler wall, reducing boiler heat transfer and subjecting the surfaces to corrosion.
