复杂锑精矿处理
treatment of complex antimony concentrate
fuzat一lingkuang ehuli复杂锑精矿处理(treatment of complexan-timony。oneentrate)用湿法、火法处理复杂锑精矿提取锑和其他有价金属的过程。复杂锑矿种类较多，主要有锑金精矿、脆硫锑铅精矿和复合锑汞精矿等。这些精锑矿成分复杂，难用选矿方法分离，冶炼工艺还不够完善。 锑金精矿处理主要采用鼓风炉挥发熔炼一贵锑电解流程和氧化焙烧一还原熔炼流程。前者经熔炼得含金粗锑即贵锑和锑氧，贵锑经氧化熔炼(灰吹)进一步分离锑后电解分离金、锑;熔炼和灰吹所得锑氧送炼锑。后者是使精矿氧化焙烧脱硫，焙砂(锑呈SbZO;)和烟尘(锑呈SbZO3)经还原熔炼得粗锑，粗锑精炼后吹炼得锑白和含贵金属的炉渣。这两种方法工艺流程较复杂。 脆硫锑铅精矿处理工业上采用流态化烙烧一还原熔炼流程。焙烧脱硫后的焙砂，加入还原煤、纯碱和石灰在反射炉内还原熔炼得铅锑合金。此流程铅锑分离不彻底，难获得高质量的金属锑，有价金属综合回收不好。曾进行过较多湿法处理的研究。 复合锑汞精矿处理有火法和湿法。火法主要采用回转窑或流态化炉氧化焙烧。在焙烧温度下，硫化汞挥发并氧化生成金属汞蒸气，然后冷凝收集。硫化锑不挥发，残留于焙砂中，焙砂送炼锑。湿法处理与锑精矿碱浸出法(见城性湿法炼锑)相同，用NaZS和NaOH溶液浸出，汞以Na:(掩S)、锑以Na3Sbs，形态进入溶液，然后用锑或其他金属置换沉淀汞，再用电解沉积法提锑，但锑消耗极高，每公斤汞耗锑达43一61kg。利用Hgs和sb侣。蒸气压的差别较大分离汞的真空挥发法，被认为是最有发展前途的方法。
