一、绪言云南个旧地区的锡矿石含有铅、锌、铜、鉍等金属。个旧市所属的革新矿向阳坡选厂和促进矿风筝山选厂处理难选氧化铅锡共生矿,生产出含Sn～10%、Pb～30%的高铅锡精矿,1973年以来就送往鸡街冶炼厂铝鼓风炉还原熔炼成铅铝合金(含Sn8%,Pb90～92%),产出炉渣含锡约在3%以上,个别高达8～9%。十多年来,已积存这种富锡炉渣10万余吨,含锡量1200吨以上。为了提高选冶回收
I. Introduction Yunnan Gejiu tin ore contains lead, zinc, copper, bismuth and other metals. Gejiu City, belongs to the renovation of the mine to Yangpo plant and promote mine kite mountain election refractory refractory tin oxide symbiotic mine production, containing Sn ~ 10%, Pb ~ 30% of the high-lead-tin concentrate, since 1973, sent To Jijie smelter aluminum blast furnace reduction smelting into lead aluminum alloy (containing Sn8%, Pb90 ~ 92%), the output of slag containing tin is about 3% or more, individual up to 8 to 9%. More than 10 years, has accumulated more than 100,000 tons of tin-rich slag, containing more than 1,200 tons of tin. In order to improve the election and recycling
