METHOD OF PROCESSING COPPER PRODUCED CONVERTER SLAG Russian patent published in 2018 - IPC C22B15/00 C22B7/04 

FIELD: technological processes.

SUBSTANCE: invention relates to processing of copper produced converter slag. In bath furnace, together with converter slag, carbon-containing fuel and oxygen-containing gas, clinker of zinc production is supplied in amount of, determined by formula M_cl=(1.0÷2.0)(3Fe_cl+14C_cl)Fe_{converter slag}/100, where M_cl – the amount of clinker supplied, kg/t of converter slag, Fe_cl, – content of metallic iron in the clinker, wt%, C_cl – clinker carbon content, wt%, Fe_{converter slag} – iron content in converter slag, wt%.

EFFECT: increase in running time of furnace is provided by eliminating the formation of a layer of partially melted clinker or magnetite particles.
