METHOD FOR PYROMETALLURGY REPROCESSING OF COPPER-CONTAINING MATERIALS Russian patent published in 2005 - IPC

Abstract RU 2249055 C1

FIELD: reprocessing of industry waste, in particular production of blister copper from recoverable materials.

SUBSTANCE: method for pyrometallurgy reprocessing of copper-containing materials includes charging of fuel as reducing agent and copper-containing material into blast furnace, introducing hot or cold wind into blast furnace; reducing fusion and blister copper separation from dross. As fuel-reducing agent metallurgical and lump oil coke in ratio of (95-0):(5-100) mass % is used.

EFFECT: reduced content of expensive coke in fuel, decreased dross efflux and copper content in dross.
