云南冶炼厂采用铜的火法冶炼,即将各矿山送来的浮选铜精矿在电炉中熔炼成冰铜,然后用转炉制取粗铜。所产出的转炉渣含铜1～3%,它不能作冶金废渣,而是返回电炉熔炼的物料。由于转炉渣中含铁高达50%左右,其中30%以上是磁性氧化铁,引起铜在电炉渣中的含量增高0.05%左右,并使电炉生产力降低25%。转炉渣的单独处理很早就为国内外的 Yunnan smelter copper pyrometallurgy, the mines will soon be sent to the flotation of copper concentrate smelting in the electric furnace into matte, and then use the converter to make blister copper. The output of the converter slag copper 1 to 3%, it can not be used as metallurgical waste, but returned to the smelting furnace. As the converter slag iron up to about 50%, of which more than 30% of magnetic iron oxide, causing the copper content in the electric furnace slag increased by about 0.05%, and to reduce the electric furnace productivity by 25%. Converter slag treatment alone as early as at home and abroad
