Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while impurity remain insoluble.These can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings. reduction, leaching, gold recovery, and tailings disposal. Once the ore is removed from the ground it is crushed in 1 to 3 stages to prepare the ore for grinding. The number and types of crushing stages is dependent on the hardness of the ore and the ore feed size required for the grinding mill. Rod mills and balls accept ore crushed to

Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill. The ... Gold is recovered using a combination of gravity concentration and cyanidation techniques. The circuit consists of primary, secondary and tertiary crushing, rod/ball mill grinding, gravity concentration, cyanide leaching, carbon-in-pulp gold recovery, stripping, electro winning and refining.
