pyrometallurgy การใช้

For further processing two basic methods are used : pyrometallurgy or electrowinning.
It combines the advantages of pyrometallurgy and a cheap reductant.
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.
Pyrometallurgy uses high temperatures to convert ore into raw metals, while hydrometallurgy employs aqueous chemistry for the same purpose.
