COPPER MATTE BOTTOM-BLOWING REFINING PROCESS AND COPPER MATTE BOTTOM-BLOWING REFINING FURNACE

摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to a copper matte bottom-blowing refining process and copper matte bottom-blowing refining furnace. Method comprises adding a copper matte and a flux to the bottom-blowing refining furnace; using a bottom-blowing spray gun to continuously blow oxygen-containing gas from the bottom of the refining furnace toward the melt in the furnace; and discharging crude copper and slag respectively.;EFFECT: improved quality of crude copper obtained, reduced oxygen consumption and longer service life of the furnace.;40 cl, 5 dwg
