Gold Extraction Methods From Three Types of Ore
Amalgamation, which uses mercury and gold particles to form an amalgam, is often used in small-scale mining operations. This type of ore is generally processed by flotation, which concentrates the gold in the non-ferrous ore concentrate and then recovers the gold during the smelting process. Gold can be obtained by cyanidation from gold …
