As a result of the processing of the material 101 diamonds with a total weight of 18,571 carats were recovered, the largest of which was 1.375 ct.
The portable sorter POLUS-M commissioned by BVSA (Pty) Ltd. at Tsodilo’s recovery facility in December 2017 is designed for the treatment of dry diamond bearing concentrate of –8 +0,5 mm size fraction with the throughput up to 100 kg/h (for –8 +5 mm). The sorter was specially designed for geological exploration in field conditions, but is also used in the field of industrial diamond enrichment in small-scale mines. Due to its small size and weight, as well as the possibility of working without the connection of compressed air and cooling liquid, POLUS-M is a universal machine for processing diamond ore with not less than 98% recovery rate. One of the main users of POLUS-M sorters is “ALROSA” group of companies, which have a total park of 21 sorters of this model.
