What is Gold Extraction? (with pictures) - wiseGEEK. 7/12/2020· Pyrometallurgy can also be used for gold extraction as well. This can include smelting, in which, the ore is reduced to a molten state as well as drying and roasting, in which other materials in the rock are oxidized to prevent them from hindering the extraction process.
