The comminution product must be 80-90% passing 75 µm. Normally, the processes is employed when the gold content is ranging from 5 to 15 g/t. The grinding circuit is the first cyanidation circuit and the ball mill works as leaching drums. Once liberation is complete, the next step is to agitate the slurry to perform a complete dissolution of gold.

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
