Improvement of processing of gold ore from a polymineral deposit in the Russian Far East

The analysis of the problems connected with development of complex ore pacers with high content of very fine-size useful components is presented. The approaches to extraction of fine and very fine fractions are discussed. With a view to ensuring ecological safety and efficiency of polymineral deposit mining, the microelements, phase composition and particle size distribution of rocks are studied. The content of clayey minerals which complicate recovery of valuable components is determined, and the elements of prevailing weight are identified: strontium, zirconium, lanthanium, cerium, neodymium, etc. The detected mineral components are highly toxic and highly mobile. Oxides of heavy metals feature high chemical reactivity. The technology developed to solve this problem minimizes leaching operations and activates recovery of fine and very fine valuable components mostly by gravity methods at the stages of pre-treatment. The proposed technology allows efficient recovery of valuable components by means of hydrodynamic and cavitation impact on clayey minerals. The leakage flux, the subsequent geochemical abnormalities and the cost of the residual concentration control in strong polymeric soap can be greatly reduced thereby.

Keywords: valuable components, microanalysis, dispersiveness, clay content, hydrodynamic activation, cavitation.
