前言某厂对脆硫铅锑矿(Pb_4 Fe Sb_6 S_(14))采取的试生产流程是,精矿经沸腾焙烧后入反射炉熔炼得到含铅60％,锑35％左右的粗合金。粗合金经反射炉氧化吹炼将锑氧化成锑氧(Sb_2 O_3)并产出含铅83％左右,锑15％—17％的底铅。底铅经电解产出精铅。锑氧再行还原熔炼产出含锑90％,铅10％左右的合金,工厂俗称“高铅锑”。粗合金的氧化吹炼,生产周期很长,生产率低,且劳动条件差。锑对氧的亲和力虽大于铅对氧的亲和力,但相差并不十分显著。故氧化分离铅锑难于彻底。铅锑分离至今
Preface The trial production process of a Pb - 4 Fe Sb_6 S_ (14) in a certain plant is that after the concentrate is roasted and roasted, it is smelted in a refiring furnace to obtain a crude alloy containing 60% of lead and 35% of antimony. The crude alloy is oxidized into antimony oxide (Sb 2 O 3) by the oxidation reaction furnace and produces lead lead with about 83% lead and 15% -17% antimony. Bottom lead produced by electrolysis of lead. Antimony Oxygen reduction and smelting output of 90% of antimony, lead about 10% of the alloy, the factory commonly known as “high-lead antimony.” Crude alloy oxidation blowing, the production cycle is very long, low productivity, and poor working conditions. Although the affinity of antimony for oxygen is greater than the affinity of lead for oxygen, the difference is not very significant. Therefore, lead-antimony oxidation difficult to completely.
