METHOD OF PYROMETALLURGICAL PROCESSING OF COPPER-CONTAINING MATERIALS Russian patent published in 2012 - IPC C22B15/02 C10B57/04

Abstract RU 2441081 C1

FIELD: metallurgy.

SUBSTANCE: reducing fuel and copper-containing stock are loaded into shaft furnace. Note here that said coke is produced by carbonising the burden containing 5 to 100% of product, the yield of volatile substances making some 14-25%, obtained by delayed low-temperature carbonisation of heavy oil residues.

EFFECT: reduced fuel consumption higher smelting rate of copper-containing stock, reduced copper content in slug.
