    01.11.2017· Mathematical models for material and heat balance in bottom-blowing smelting, converting, anode furnace refining, and electrolytic refining were established based on the principles of material (element) conservation, energy conservation, and control index constraint in copper bottom-blowing smelting. Simulation of the entire process of bottom

  • Copper Smelting Process - Furnaces Used, By

    Sulphuric dioxide gas is created in smelting copper process and is converted sulphuric acid which is used in some of the smelting processes or sold as a by-product. Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular

    Copper processing - Copper processing - Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or

  • what is copper matte - Chemistry - - 7035456 |

    Matteis a term used in the field of pyrometallurgy given to the molten metal sulfide phases typically formed during smelting of copper,nickel, and other base metals. Typically, a matte is the phase in which the principal metal being extracted is recovered prior to a final reduction process (usually converting) to produce a crude metal. Mattes may also be used to collect impurities from a metal

The furnace matte is then transferred to the converter aisle to further reduce the iron content and concentrate the pay metal content. The final product from the converter aisle is a matte containing 2% iron which will be destined for our refinery in Kristiansand, Norway

  • How to Choose Gold Smelting Flux - Superb

    Smelting is an integral part of the refining process of gold and other precious metals. It is the major part of refining where the precious metal (gold in this case) is melted out of its ore. Metal ores often contain a lot of other elements and impurities, smelting is therefore important in removing these. Gold smelting flux is often added to the ore during the smelting process.
