The gold milling process may be broken down into three basic procedures: (1) Sorting the ore by size (2) Crushing the rock (3) Extracting the gold . First, miners raise the ore out of the mine in wheeled carts pushed on rails and take it down to the mill. The rock fragments are sorted according to size in a grizzly, a device consisting of a series of spaced bars, rails, or pipes, above a ...

More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding ...

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 recovering the gold from ore in the past. The ore now ...
