The first case study deals with recovering gold reef from surface rock dumps (SRD) at Kloof Gold Mine. Over a period from 2003 to 2010 various test work campaigns and pilot plant work was carried out proving both the technical and economic viability of optical sorting. Typically the grade of a SRD ranges between 0.5 g/t to 1.0 g/t of gold.

Gold Extraction Methods From Three Types of Ore
However, extracting gold from quartz vein gold ore is a meticulous process that requires careful planning and execution. 1. Cyanide gold extraction includes crushing, leaching, filtering, adsorption, elution, etc. The first step in the method is crushing the quartz into small pieces. This can be done using a jaw crusher or a mortar and pestle.
