FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

FLOWSHEET OPTIONS CRUSHING FOLLOWED BY DUMP OR HEAP LEACHING WITH CYANIDE This method of gold recovery is the preferred method for treating low-grade gold ores because of its low cost. Between 10-20% of the gold recovered each year from primary sources is extracted by this technique. The advantages of this process are: • Simplicity

Double-Refractory Carbonaceous Sulfidic Gold Ores

Jan 01, 2016· Gold in refractory sulfide ores occurs as fine inclusions or in solid solution typically within pyrite, marcasite, and arsenopyrite grains. In this type of ore, because the gold is encapsulated, the interaction with cyanide to form the soluble metal complex is inhibited (Marsden and House, 2006, La Brooy et al., 1994).

Gold Leaching Plant Flowsheets Gold Metallurgy

May 02, 2016· The Kalgoorlie ore deposits occur in Pre-Cambrian rocks and essentially consist of calc schist and quartz-dolerite-greenstone. The ores contain free gold and tellurides. Auriferrous pyrite is the most abundant sulphide and is occasionally associated with chalcopyrite, tetrahedrite and arseno-pyrite. The gold associated with the pyrite is in a very fine state and is not liberated

Designing gold extraction processes: Performance study of

Aug 01, 2017· The flowsheet design is significantly different for sulfidic gold ores compared to other types, such as free milling ores, because sulfides consume cyanide during leaching. Therefore, three mineral attributes were selected to describe the sulfidic mineralogy of the ore: Arsenic sulfide,Copper sulfide,and Iron sulfide .
