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.
Ore processing is highly important, particularly in the production of precious metals and non-precious metals. This process uses decanters in various mining applications: gold and silver, lead and zinc, nickel and copper, platinum, lanthanoids.
Screening 101. Screening is the passing of material through definite and uniform apertures is the only true and accurate means of grading to a required particle size. Air separation and hydraulic classification depend upon gravity and particle shape, and result in the segregation and retention of material of higher specific gravity and lower ...
Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and. Hashing (extraction/recovery) In the context of flowsheet selection, the bashing and mashing stages are relatively straightforward.
The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the ...

There are several technologies that may be applicable for preconcentration including: gravity concentration, screening, sensor based ore sorting (SBOS) and magnetic separation. The suitability in each case depends on the ore properties as well as site and economic conditions.
A "refractory" gold ore is an ore that has ultra-fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. A refractory ore generally contains sulphide minerals, organic carbon, or both, generally leading to a …
