Iron Ore Micron Gold And Sulphides

was the main copper-bearing mineral in the ore but secondary copper sulphides such as covellite and bornite were also present. The ore was rich in pyrite and the total content of sulphides was about 10 %. Most of the gold was finely disseminated in pyrite and arsenopyrite. The main portion of the gold particles was less than 1 micron.

Gold extraction - QueensMineDesignWiki

2019-6-28 · Reactive sulphides containing gold, such as pyrrhottite, can require high amounts of oxygen as the iron (II) is oxidized to iron (III), and sulphide to sulphate (Brooy, 1994). Oxidant addition is employed in these cases to meet oxygen demands, and can be controlled by an oxygen electrode inserted into the leach tank.
