Mineral sorting techniques with advanced texture analysis

摘要

Optical sorting and identification is widely used by a number of different industries, including metals, glass and plastics recycling, as well as mineral processing. Lately, the importance of sorting minerals more efficiently in order to maximise recoveries from lower ore grades has created new requirements and needs for separation generally. In response to this industry trend, Norway-headquartered Comex AS has developed a new optical sorting system, based on complex image analysis, which can be used for both material sorting and identification or characterisation, without the need for prior separation.
