在火法炼铜中,冰铜吹炼所产转炉渣,通常直接返回熔炼炉处理,一般含有15—30%Fe_3O_4,常导致渣含铜上升,铜在渣中的损失增大,以及操作困难等。为克服这一缺点,近二十余年发展采用各种单独处理的方法,选矿法是其中之一。此法对铜的回收率比直接返回熔炼炉约高10%左右,而尾矿有可能作为炼铁原料或 In pyrometallurgical copper smelting, the converter slag produced by the smelting usually returns directly to the smelting furnace and generally contains 15-30% Fe 3 O 4, which often leads to the increase of slag copper content, the increased loss of copper in the slag, and operational difficulties Wait. To overcome this shortcoming, nearly 20 years of development have adopted a variety of separate treatment methods, beneficiation is one of them. This method of recovery of copper than the direct return to the melting furnace about 10% higher, while the tailings may be used as raw material for iron or
