用烟化爐处理氧化鉛鋅矿主要的根据是矿石造渣成份属于低熔点范围,因此可以用反射爐預先熔化,然后送烟化爐吹炼。试验时发现:矿石不能在氧化气氛的反射爐中很好地熔化,但是如果在爐料中适当地加入还原剂(煤或焦粉),改变造渣条件后,熔化問题是可以解决的。在用还原剂基本解决反射爐熔化问题后,曾将各种矿石物料用各种不同比例配料进行熔化与吹炼試验,结果得出,只要配料成份适当,各种矿石物料都能处理,用烟化爐方法揮发富集氧化鉛锌矿中的鉛、鋅及锗等有价金属是成功的。一、矿石物料及燃料试验用铅鋅矿石主要为下述六种氧化矿。 (一) 铅鋅混合脉矿:特征为氧化铁、氧化钙与二氧化硅在百分組成上看能构成低熔点爐渣,但鉄以
The main basis for the treatment of lead oxideite with fuming furnaces is that the ore slagging components belong to the low melting point range and can therefore be premelted in a reverberatory furnace and then passed to a fuming furnace for blowing. It was found during the test that the ore did not melt well in the reverberatory furnace in an oxidizing atmosphere, but if the reducing agent (coal or coke) was properly added to the charge, the problem of melting could be solved by changing the slagging conditions. After using the reductant to basically solve the melting problem of the reverberatory furnace, various kinds of ore materials were melted and blown with various proportions of ingredients and the results showed that as long as the ingredients of the ingredients were appropriate, various ore materials could be handled and smoke Furnace method volatilization enrichment Lead, zinc and germanium and other valuable metals is successful. First, the ore materials and fuels test lead-zinc ore mainly for the following six kinds of oxide ore. (A) lead and zinc mixed vein: characterized by iron oxide, calcium oxide and silicon dioxide composition in terms of the composition of low melting point slag, but 鉄 to
