Performance evaluation of optical sorting in mineral processing - A case study with quartz, magnesite, hematite, lignite, copper and gold ores

Results showed that the performance of the VIS type optical sorter mainly depends on correctly sorted amounts of valuable and non-valuable particles. Alongside with the evaluation of change in sorting performances in accordance with feed rate, ore type, and particle size; pre-concentration of copper and gold ores, concentration of hematite from alkaline waste, dry cleaning of lignite and market quality magnesite and quartz sorting applications with VIS type optical sorter were also discussed.
