METHOD FOR COMPLEX PROCESSING OF SLAGS OF COPPER-SMELTING PRODUCTION Russian patent published in 2024 - IPC C22B7/04 C21B11/00 C21B3/04 

FIELD: non-ferrous metallurgy.

SUBSTANCE: invention can be used for non-waste processing of copper smelting production slags with production of commercial products, such as cast iron and crushed stone, suitable for further use in metallurgy and as construction materials. Method for complex processing of slags of copper smelting includes carbothermic melting of charge, which is carried out in a single-step mode of a mixture of the following composition: initial slag, a reducing agent, lime and liquid glass, with the following ratio of components, 1:(0.23–0.25):(0.27–0.30):(0.05–0.08). Before melting, components of the charge are briquetted, melting is carried out at temperature of 1,380–1,500 °C to obtain alloyed cast iron and silicate slag.

EFFECT: method provides non-waste processing of slags from copper-smelting production with obtaining alloyed cast iron and silicate slag.
