The invention relates to a crude
copper blowing process in the technical field of crude
copper smelting. The process comprises the following steps of mixing
copper-containing waste materials and copper-containing
waste treatment tailings, then adding into a side blowing
melting furnace, adding a co-
solvent, a
reducing agent and fuel, simultaneously blowing
oxygen into the furnace, and carrying outmixing and blowing at 1200 to 1250 DEG C; and separately discharging blowing
tailings, the crude copper and
flue gas, and carrying out discharging after the
flue gas is treated. The
melting point oflimestone is low, so that melting of
quartz stone and
iron oxide can be promoted, and the fluidity can be improved. Iron,
molybdenum,
magnesium,
calcium,
silicon and the like in the furnace charge areoxidized to form
oxide in an
oxygen-rich environment, and the
oxide is combined with the
quartz stone to form
tailings, so that the non-
copper metal elements are separated from copper, copper in
copper oxide and
copper sulfide can be reduced through the
iron oxide, and the copper content is improved; semi
coke is used as fuel, and the content of
fixed carbon is high, so that sufficient energy isprovided for
combustion, the
chemical activity is high, and the effect of a
reducing agent can also be achieved; and the
reduction rate of the copper can be improved through the cooperation of the several chemical meterials.
