Optical sorting machine become more and more popular in mineral processing industry now.
Optical sorting (sometimes called digital sorting) is the automated process of sorting solid products using cameras and (or) lasers. Then separation system uses compressed air for small products and mechanical devices to separate the mineral particles based on color differences.

It can improve the grade of raw ore fed into crushing and grinding system, reducing the feeding quantity to tertiary crushing and grinding system so as to save the power consumption and improve the efficiency of the later beneficiation process.

After 10 years practical operation in quartz, feldspar, talc, limestone, calcite, barite, garnet, gold ore, copper ore, Prominer and our partner can provide the optical sorting system and undertake the pilot test in our factory.
