FIELD: natural minerals dressing, method is used for fine gold extraction from tailings of industrial devices in particular. SUBSTANCE: pulp is fed in inclined chute and it is subjected to action of upgoing stream of liquid through lattice in chute bottom with temperature of no less than plus 40 C under pressure of 0.3 - 0.5 atm and then it is fed in downgoing stream of pulp by small sprays with diameter of 0.2 - 0.4 cm through lattice located slantingly at an angle from 10 to 29 deg to meeting stream. Holes in lattice are made round. EFFECT: improved process. 2 dwg
