The products of the copper removal process are: waste slag containing Table 2. Composition of copper concentrates processed in Poland and in the world [3].
sulfide concentrate, mainly chalcopyrite, which Atlantic Copper receives from the worldclass Grasberg mine in Indonesia [5], smelting approximately one million tons of concentrate per year. The Huelva smelter has been operated with Outokumpu flash smelting technology [6] .
Copper flash smelting is a relatively new process which has been in operation since the 70's and is a pyrometallurgical process used in conjunction with copper sulphide concentrates. The main key facilitators produced by the process include controlled oxidation of Fe and S, a large evolution of heat and the effective melting of solids.
Flash furnace smelting combines the operations of roasting and smelting to produce a highgrade copper matte from concentrates and flux. In flash smelting, dried ore concentrates and finely ground fluxes are injected together with oxygen and preheated air (or a mixture of both), into a furnace maintained at approximately 1000°C (1830°F).

furnaces cuts total smelting and refining energy requirements by onethird. The use of leaching and solvent extraction eliminates smelting and converting altogether, Further conservation is possible, however. This chapter reviews the energy requirements for the various stages of copper production, in
Dec 20, 2013· Oxygenautogenous flash smelting of lead concentrates followed by slag reduction by injection coal in an electric furnace has been developed and is ready for commercial application. Pilotplant studies demonstrate that the process works. Pilot studies have established process characteristics. The process is easily controlled.
Nowadays, more than half of the world's copper is manufactured using flash smelting technology. The invention brought Outokumpu international success in copper, nickel, cobalt, zinc, steel, and sulfuric acid technologies, and the company began establishing sales offices in Canada, the United States, Mexico, Brazil, Chile, and Peru.
This text has 20 chapters and begins with an overview of flash smelting and its products; the main raw materials of copper flash smelting; chemical reactions in the flash furnace; impurities in the concentrates that are fed to the flash furnace; and the operation of industrial flash furnaces.

Flash smelting Flash smelting is a smelting process for sulfurcontaining ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production.
lean blister copper is stable, and secondly, the chemistry of feed mixture gangueof the smelter. It differs from most copper concentrates, in particular as to its concentrations of alumina as well as magnesia. The fluxing practices at the smelter also include lime additions. 18. The slag also has a relatively high K. 2. O concentration.
General Boliden Harjavalta comprises two plants – the smelter in Harjavalta, which produces anode copper, and the refinery in Pori, where copper anodes are refined into copper cathodes. At the Harjavalta smelter Boliden Harjavalta also carries out nickel smelting on a tolling basis.
Copper smelting with the Outokumpu flash smelting process generates significant amounts of SO 2rich offgas and flue dust. From the smelting unit, gases with a dust load are directed into a heat recovery boiler (also known as a waste heat boiler). In the radiation section temperature decreases, sulphates become thermodynamically stable,
Nov 12, 2008· Flash Smelting Process 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 their facility in Harjavalta, Finland. The technology has been continuously developed to meet the industry needs.
Flash smelting is a pyro metallurgical process for smelting copper sulphide concentrates as well as nickel sulphide concentrates (Figure 2). Besides the main elements, copper,

Smelting Concentrates. Additional fluxes, when needed, are added to the charge, in the number 4 Mace blast furnace. Siliceous mine ores supply the silica and beach coral the lime. Ten to 12 tons of concentrates can be reduced to 1 ton of matte which contains 40 .
Description. Attention then turns to Outokumpu flash smelting, Inço flash smelting, and mathematical representation of flash smelting. The chapters that follow focus on the effects of blast preheat on flash smelting; the combustion of fossil fuel in the flash furnace; and the effect of matte grade on the fossil fuel, industrial oxygen,...
flash smelting. n. (Metallurgy) a smelting process for sulphurcontaining ores in which the dried and powdered ore, mixed with oxygen, is ignited on discharge from a nozzle, melts, and drops to the bottom of a settling chamber. Sulphur is released mainly in its solid form, thus reducing atmospheric pollution.
