FIELD: concentration of ground ore and sands in gold and platinum gravel deposits. SUBSTANCE: method of centrifugal vibration separation of mixtures (pulp) includes delivery of pulp to bowl by means of circular riffles revolving around its axis and in planetary pattern. Prior to delivery of pulp, grains of solid materials at density ranging from 7.0 to 20.0 g/cu.cm and size not exceeding 0.5 height of riffle are introduced. EFFECT: enhanced extraction of required components from fine-grained mixtures. 2 dwg
