Sorting in Industrial Minerals

Automated optical ore sorting equipment is used by major mining companies for industrial minerals projects. Ore sorting systems allow mining operations to reduce dilution, lower strip ratios and transport costs, remove contaminants and optimize process flows by separating ore from gangue on a rock by rock basis.

Color sorting machines have been used in mineral industry to pre-sort recovered material or enrich minerals of value. Owing to further development and model upgrading, these machines are now very reliable and produce good results, as long as the color differences display a good correlation with the materials to be separated. This applies, for example, to calcium carbonate used in industries producing filling substances. In addition, an important fundamental condition for the success of color sorting lies in the availability of surfaces free of dirt and dust.
