复合锑汞精矿处理
treatment of complex antimony- mercury concentrate
fuhe tigong lingkuang ehuli复合锑汞精矿处理(treatment。f。omplexantimony一mereury eoneentrate)从锑汞精矿中分离回收锑和条的过程，属复杂禅精矿处理范畴。精矿中的主要矿物成分是硫锑汞矿(HgS·ZSbZs3)，一般含锑20%一45%，含汞1%~5%，可用火法或湿法处理。火法有流态化焙烧法、回转窑燕馏法。火法分离锑和汞，大多采用低温焙烧，使汞优先挥发，然后从焙烧砂中提取锑。 流态化焙烧法是将复合锑汞精矿送入流态化焙烧炉内于703一753K温度下进行氧化焙烧，使汞优先挥发，少量Sb多3脱硫，挥发的汞进入炉气然后冷凝回收(见汞蒸气冷凝)。焙烧时严格控制炉内弱氧化性气氛以防止锑过度氧化生成Sb:O‘，使锑呈Sb:03留在焙烧砂中。然后按一般锑精矿处理方法回收锑。前苏联采用处理能力为90~10ot/(mZ·d)的流态化焙烧炉处理锑汞精矿时，锑和汞的提取率分别为90%和96%一97%。 回转窑蒸馏法的炉温为923K，控制燃烧的空气量，使炉内呈中性或还原性气氛，保证离炉气体中游离氧不大于0.5%。汞呈硫化汞直接挥发，硫化锑则少量氧化留于焙砂内，达到硫化锑和硫化汞分离的目的。挥发的硫化汞从窑的排渣端进入燃烧室经氧化生成汞蒸气，经冷凝后回收，含硫化锑焙砂再氧化挥发回收锑(见锑精矿鼓风炉挥发熔炼)。 复合锑汞精矿湿法处理是用硫化钠碱性溶液浸出，使锑、汞都呈复合硫化物形态〔Na3SbS3，NaZ(H 952)〕进入溶液，然后用铁或硫置换沉淀析出金属汞或硫化汞，分离出汞或硫化汞后，溶液送电解沉积锑(见碱性湿法炼钵)。用元素硫沉淀出硫化汞，无金属汞析出，可保证生产现场有较好的工业卫生条件。
