[0029] Describe in detail below in conjunction with accompanying drawing of the present invention:
[0030] The principle of oxygen-enriched copper blowing in a blowing furnace of the present invention is: it is equivalent to air blowing, the air blown into the high-temperature melt through the spray gun and the matte in the furnace undergo an oxidation reaction, and the sulfur and oxygen in the matte The sulfur dioxide generated by the reaction enters the flue gas treatment system, the iron in the matte is oxidized and slags with the flux, the copper is purified, and finally produces blister copper with a grade of more than 98.6%. Oxygen-enriched blowing makes the oxidation reaction of sulfur and iron more intense due to the increase of oxygen concentration, but at the same time brings a more serious risk of slag foaming.
[0031] Such as figure 1 Shown is a process flow diagram of a method for oxygen-enriched copper blowing in a blowing furnace of the present invention. Th...
