The process design of gold leaching and carbon in pulp

The ore is first reduced in size typically 80 passing 75µm to ensure that all non refractory gold is readily accessible for cyanide leaching There are several variations of comminution circuits used in the gold industry such as Multi stage crushing and pebble and/or ball milling

The grinding circuit consists of two parallel lines each having one twin pinion semi autogenous SAG mill 36 X20 and one twin pinion ball mill 26 X40.5 The gravity circuit currently recovers approximately 25 of the gold The remaining gold in ore is sent to cyanidation followed by carbon in pulp CIP gold recovery.

Energy and Cost Comparisons of HPGR based Circuits

Up until now tumbling mills such as AG/SAG mills and ball mills have had a dominant bearing on the design and economics of comminution circuits However it is commonly agreed that the majority of employed comminution processes are energy intensive and energy inefficient accounting for up to 80 of overall process plant energy consumption and having an efficiency of as low as 1 .
