Ore processing consists of the following stages: Crushing and grinding of the ore. Addition of process water (generally decanted from the tailings pond) to form a slurry. Addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution. Addition of carbon to adsorb (attach) dissolved metals and remove ...

The Goldstrike mine has feeds from three different ore deposits. One open pit mine, and two underground mines (Wikipedia Contributors, 2016) (Tsia, 2008). Each of the sources has slightly different mineralogy, requiring a flexible approach in the processing of the feed stock. Gold commonly found within mining is usually alloyed or bonded to another

Sensor-based ore sorting is a physical separation technology where the mechanical platform contributes to the overall process efficiency. The primary factor for technical feasibility is the sub-process of detection. The detection efficiency describes the chance of misclassification in dependence of the cut-off grade.
