What Is Gold Extraction With Pictures

In some cases, gold cannot be removed by cyanidation alone. 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.

Guides For Highsulfide Gold Processing

Mar 17, 2020 High sulfide gold ore refers to a certain gold ore with 20% -30% of gold wrapped by sulfide (mainly pyrite). Because most of the gold in high-sulfide gold ore exists in the form of sulfide-encapsulated gold, when using direct leaching process, the consumption of gold leaching agent and cost of gold leaching production will increase, and gold processing efficiency is not good.

Mary McMahon When gold is mined, it must be extracted from its surrounding materials. Gold smelting is a metallurgical process used to separate metal from ore, rocks that contain gold. The ore is ground and treated with chemicals to remove some impurities before being heated at high temperatures with a flux that triggers a chemical reaction, causing the metal to precipitate out of the mixture.
