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 ...
An entirely new, revolutionary energy-efficient flash smelting method for copper concentrates was developed in Harjavalta and introduced in 1949. The flash smelting method has been un-der continuous development over the years, and is today the most widely used smelting method for copper concentrates in the world. Ten years later, the smelter in Harjavalta was also the first in the world to ...

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 ...
The effectivity of present copper smelting technologies have their roots in industrial and laboratory-scale experience accumulated over the past decades. Since early ‘60s, the tools for improving the processing conditions and smelting vessel design included scale modelling and manual computing of homogeneous multicomponent equilibria. The scale models were isothermal, room temperature ...
Flash smelting (Finnish: Liekkisulatus, literally "flame-smelting") is a smelting process for sulfur-containing ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper

The technology was first introduced at Outokumpu's Harjavalta smelter in Finland in the late 1940s. Thanks to flash smelting - as well as optimal process configurations and a novel Outokumpu-developed nickel process - Harjavalta is today among the world's cleanest copper smelters. After the smelter's extensive expansion and modernization in 1993-96, which increased copper smelting capacity by ...
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. Flue ...
So-called flash smelting techniques have therefore been developed that utilize the energy released during oxidation of the sulfur in the ore. The flash techniques reduce the energy demand to about 20 million Btu/ton of produced cathode copper. The SO 2 concentration in the off gases from flash furnaces is also higher, over 30%, and is less expensive to convert to sulfuric acid. (Note that the ...
11/06/2019 The energy consumption of flash smelting has further decreased by approximately 20% since then due to the extensive development work that has taken place both at the Outotec Research Center in Pori, Finland and in cooperation with operators of the technology in many countries across the globe. The development path of flash smelting has seen various moves into different commodities
01/12/2010 The flue dusts studied here was a sample from a flash smelting furnace. Several kg of this sample were collected from the furnace and according to the researchers of the company is representative of the copper smelter flue dust generated there. This sample was exhaustively characterized by X-ray fluorescence (XRF), scanning electron microscopy (SEM) in conjunction with

The aim of this project is to develop and modernize Khatoon Abad Copper Smelting Plant with a production capacity of 120,000 tons of anode copper per year. Khatun-Abad copper smelting plant with a nominal capacity of 80,000 tons of copper anode with a purity of 99.4% was operating using flash furnace technology.

The flash smelting process is used widely around the world to extract primary copper. Smelting of sulphidic copper ores produces flue dust containing SO2-rich exhaust gas, causing corrosion problems in the gas cleaning equipment of the process, especially in the heat recovery boiler. The aim of this thesis was to understand the corrosion mechanisms of the boiler steels and to determine what ...
In 1949 Outokumpu introduced autogenous Flash Smelting of copper concentrates at their facility in Harjavalta, Finland. The technology has been continuously developed to meet the industry needs. After the spin-off of Outokumpu Technology from Outokumpu Group in 2006 and the name change of the company to Outotec in April 2007, the Flash Smelting Process became part of a wide range of ...
