Ores and Minerals Introduction Extraction

Ores and Minerals Introduction Extraction

Before applying all these methods of extraction of metals according to their reactivity, concentration of ores is done. Ores are found in nature with many impurities such as rock particles, sand and other impurities. These impurities in an ore are called matrix or gauge. The removal of matrix or gauge from the ore is called concentration ore.

Gaolong, Lannigou and Donbeizhai (all in China) can influence the behaviour of gold in flotation, leaching and/or recovery processes. Electrum with a high silver content may give poor gold extraction due to tarnishing of the silver (Fleming, 1998). The presence of copper in the ore at above 0.3% concentration may make direct cyanidation ...

Silver and gold are extracted by the cyanide process (Mac Arthur - Forrest process). After the preliminary crushing and concentration by froth floatation process, the ore (crushed auriferous rocks in the case of gold) is leached with dilute (0.4 - 7%) solution of sodium cyanide made alkaline by adding lime kept agitated by a current of air.
