FIELD: natural minerals dressing. SUBSTANCE: slick concentrate, using size screening procedure, is divided for two fractions: big size fraction, that after nuggets of gold are separated, goes to waste, and small size fraction, that is subjected to separation to select particles of scale form and concentration on table is sent for amalgamation. Grain-type particles after separation go to sedimentation. Mercury-bearing particles are separated from tailings of sediment and also are sent for amalgamation. Concentrate of sediment is subjected to additional concentration on table. Table concentrate is also sent for amalgamation. Intermediate products of tables and tailings of amalgamation are sent back for separation. Nugget gold and slick metal from amalgamation output are sent for refining. EFFECT: improved gold extraction process. 3 cl, 2 dwg
