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 ...

This chapter discusses the process of direct-to-copper smelting that is the smelting of concentrate directly to molten copper in one furnace. In 2011, it was practiced in three smelters: Olympic Dam (Australia), Glogo´w II (Poland), and Chingola (Zambia). All of these plants use an Outotec flash furnace.

Jul 25, 2019 Flash smelting (Finnish: Liekkisulatus, literally "flame-smelting") is a smelting process for sulfur-containing ores [1] including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. [2] [3] It has also been adapted for nickel and lead production. [2]

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.

Apr 01, 2014 1. Introduction. The flash smelting process is widely used throughout the world for copper production, accounting for about 50% of global capacity for primary copper production .A Copper Smelter in China has operated an Outotec type flash smelter for about 30 years.Due to the sources of clean deposits are progressively depleted, the copper concentrate involving copper are

Flash Smelting has been well established in the copper and nickel industries and lead smelting has also been tested on a production scale in a pilot plant in Finland. During flash smelting the copper containing raw material, together with aggregates, is added to the furnace chamber; in addition, an oxygen-rich gas is also fed into the chamber.

Copper smelting with the Outokumpu flash smelting process generates significant amounts of SO 2-rich off-gas 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,
