Gold extraction - QueensMineDesignWiki

Although there are various leaching techniques for free-milling ores, the main technique in Australia, North America, and South Africa is agitation cyanide leaching. Gold recovery is then attained through carbon-in-leach (CIL) or carbon-in-pulp (CIP) methods (Brooy, 1994). The figure below from Lima (2007) shows a typical CIL/ CIP process.

In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput.

Ore processing – Waihi Gold

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in the leaching process.
