What is Gold Extraction? (with pictures) - Info Bloom

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.

How gold is made - history, used, parts, procedure ...

Gold is generally found in two types of deposits: lode (vein) or placer deposits. It is usually extracted from lode deposits by drilling or blosting, whereas placer deposits require hydraulic mining, dredging, or power shoveling. Once extracted, the gold ore is pulverized to prepare it for refining.
