Gold ore was crushed successively in a primary and

Gold ore was crushed successively in a primary and then in a secondary crusher. Product from the secondary crusher analysed 80% passing 2000 mm. The object was to further reduce the size by grinding to achieve the liberation size of 45 mm. It was, therefore, ground in a wet rod mill 2.85 m × 4.27 m using steel rods of 4.11 m in length.

Double-Refractory Carbonaceous Sulfidic Gold Ores

2016-1-1 · 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).
