FIELD: mining.SUBSTANCE: invention relates to the metal mining industry and can be used for processing of gold-containing concentrates, mainly quartz, carried out prior to gravitational enrichment. The method of processing gold-containing concentrate prior to enrichment comprises supplying pulp into cavitation dispersion medium, dispersion with opening the grains of gold particles on zones of their natural adhesion with the rock. Processing of the pulp is carried out in stator-free rotary-pulsation unit, at the output of which the flow of the pulp is additionally processed by two turbulence promoters mounted on the pulp pipeline, each of which represents a swirler mounted inside the pipe. The flow of pulp processed in the rotary-pulsation unit is first directed as co-current to the first turbulence promoter, the swirler of which is mounted in the pipe with a diameter equal to the diameter of the pulp pipeline, then tangentially - to the second turbulence promoter, the swirler of which is mounted in the pipe of larger diameter, smoothly passing in the diameter at the outlet of the second turbulence promoter, equal to the diameter of the pulp pipeline.EFFECT: improvement of efficiency of gold extraction.3 dwg, 2 tbl, 1 ex |
