What is Gold Extraction? (with pictures)

2021-2-24  Various mineral processing methods are used, often in conjunction with one another, to extract the ore from its rock encasement. Comminution, hydrometallurgy, and pyrometallurgy are used to extract the gold. Comminution is often one of the first steps in gold extraction. Extractors break apart the hard rock containing the ore.
