CHAPTER 11 - ORE SORTING - A process for separating mineralised ore from associated waste products from large particle sizes using differences in texture, colour etc. - Benefits: 1. Only mineral bearing ore would be subjected to costly crushing/grinding operations. 2. Small equipment needed for downstream recovery. 3. Environmental benefits through the rejection of gangue particles of larger sizes. 4. Usually recoveries are in ~ >90%. - It involves the appraisal of individual ore particles for acceptance/rejection. - Size range ~ 8-160 mm

- A modern sorter has four primary units: 1. Feed presentation system Serves to present the incoming feed material to the sensing and separation system in a stable manner, i.e. at known velocity and trajectory – usually in a mono layer and in narrow streams. 2. Sensing system Measures a given property, e.g. colour, reflectivity, etc. 3. Decision making system Usually a computer to decide on the acceptance or rejection of the measured particle. 4.
