METHOD OF ELECTRO-PHYSICAL ENRICHMENT OF THE PULP CONTAINING FINE-DISPERSED GOLD Russian patent published in 2004 - IPC

FIELD: enrichment of natural minerals.

SUBSTANCE: the invention is dealt with a method of enrichment of the of natural minerals, namely, with electrical separation of the fine-dispersed gold from gold-bearing loose sandy and sandy-argillaceous mucks. Technical result - increased degree of extraction of the fine-dispersed gold, decreased power inputs. The method provides, that electrical separation of the gold-bearing pulp is conducted in the moving solution of chlorides of alkali metals with concentration of 10-20 g/l in the alternating electric field created by electrodes at feeding to them of an alternating voltage of 12-18 V.

EFFECT: the invention allows to increase a degree of extraction of the fine-dispersed gold and to decrease power consumption.
