Sep 29, 2021· The ore sorting process helps concentrate the metals of commercial interest from the Kutcho deposit, which are principally associated with high density sulphide minerals. Rocks are individually scanned, and low grade (low density) waste material is selectively diverted away from downstream processing using compressed air jets.

Jan 12, 2018· Advances in electronics and optical technology have made the automation of sorting techniques an important process in some ore systems. For example, recent advances using optical sorting methods is being employed in the diamond industry using an xray beam. Diamonds emit light when hit by an xray and the resulting light is picked up by a detector.

May 12, 2020· Ore sorting is a very broad concept that includes sorting by grade, particle size, and mineralogy across many different mineral processes. Continuous analysis of ore in base and precious metal applications is best accomplished using rapid online elemental analysis, with either PGNAA (Prompt Gamma Neutron Activation Analysis) or PFTNA (Pulsed Fast Thermal Neutron Activation).

In southern Africa, two xray sorters are used to preconcentrate sulphide gold ore into two different grain size categories. While the input material has an average gold content of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%. Chromite.

Ore sorting can run into capacity and efficiency issues if particles are below 30mm. In contrast, dense medium separators can sort particles down to 0.75mm in size. If youre working with finer particles, dense medium separation is the way to go. Higher tonnages can also be accommodated with dense medium separation.
