DEVICE FOR ENRICHMENT OF GOLD-BEARING SULPHIDE MINERAL MATERIAL Russian patent published in 2023 - IPC C22B11/12 F27B17/00 

FIELD: non-ferrous metallurgy.

SUBSTANCE: invention relates to pyrometallurgical devices for extracting dispersed gold from hard mineral material. The device contains a cylindrical heat-resistant container and a heating source for melting gold-bearing sulphide mineral material in a heat-resistant container containing an upper slag part located above the lower matte part, which are equipped with drain pipes for alternately discharging melts. The heat-resistant container for discharging the matte weighted with gold drops from it is rotatable and provided with a looped chute made on the inner wall of the upper slag part, which is provided with a tangential branch pipe. The looped chute is made above the drain branch pipe for molten slag installed in the upper slag part of the heat-resistant tank above the matte level. The lower matte part is made in the form of a part of a sphere with a drain pipe for draining the depleted matte melt on the vertical axis.

EFFECT: increasing the gold extraction efficiency.
