DEVICE FOR BENEFICIATION OF GOLD-BEARING COPPER-NICKEL SULPHIDE MATERIAL Russian patent published in 2024 - IPC C22B11/02 F27B17/00 C22B9/05 

FIELD: non-ferrous metallurgy.

SUBSTANCE: invention relates to nonferrous metallurgy, particularly to pyrometallurgical devices for extraction of microdispersed gold from refractory ore and technogenic materials. Device for beneficiation of gold-containing copper-nickel sulphide material, comprising a vertical heat-resistant container, made with possibility of heating, melting and blowing with neutral gas of molten material, divided into matte and slag parts of the melts, equipped with a drain pipeline for draining slag, side branch pipes for supplying gas under pressure for blowing molten slag, located above the drain pipeline for draining the slag melt, and dispenser, wherein the vertical container is equipped with a heat-resistant grid made of separate hollow ceramic tubes bent into a ring, and to ensure the supply of neutral gas along the entire cross section of the slag melt, said hollow ceramic tubes comprise holes made along the inner and outer perimeter of the walls of the side parts of the hollow ceramic tubes, which are directed towards the vertical axis of the heat-resistant container and towards the side wall of the heat-resistant container, and the cavities of the hollow ceramic tubes bent into a ring and the gas supply branch pipe are interconnected, wherein rows of holes of each ring are staggered relative to adjacent rings.

EFFECT: beneficiation of gold-bearing melt of matte and depletion of gold-bearing melt of slag.
