pyrometallurgy

For further processing two basic methods are used: pyrometallurgy or electrowinning.

It combines the advantages of pyrometallurgy and a cheap reductant.

The complement to hydrometallurgy is pyrometallurgy, which is usually older technology.

In the pyrometallurgy division improved or new pyrometallurgical processes are researched and developed.

In pyrometallurgy, the metal ore is first oxidized through roasting or smelting.

Unit processes are usually broken down into three categories: pyrometallurgy, hydrometallurgy, and electrometallurgy.

These specialties are generically grouped into the categories of mineral processing, hydrometallurgy, pyrometallurgy, and electrometallurgy.

The scope of electrometallurgy has significant overlap with the areas of hydrometallurgy and (in the case of fused salt electrolysis) pyrometallurgy.

Matte is 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.

Extractive metallurgy of ferrous and non-ferrous metals can involve pyrometallurgy, but chemical processes like hydrometallurgy and electrometallurgy are far more common in method of non-ferrous extraction.
