The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device ...
An excavator removes any residual steel or explosives before it is fed into the mill for processing. Processing. Gold at Macraes is known as 'refractory ore', which means it is ultrafine and resistant to the typical cyanide leach process, typical of most gold processing plants. This refractory nature of the ore led to inefficiencies ...
