| 摘 要： | 本文采用低温氯化-蒸馏法处理高砷锑烟尘,使砷与锑达以分离;砷的回收先用Na_2S使其沉淀为As_2S_3,再用CuSO_4溶液浸出,然后浓缩、结晶出As_2O_3;锑的回收采用升温蒸馏法获SbCl_3。该法流程和设备较简单,砷锑分离彻底,污染小,试剂消耗低,产品纯度均高达99.9％以上,有显著的社会效益和经济效益。

| Abstract: | Low temperature chlorination leaching-distilling process is adopted in this paper to treat smoky dust with high content of arsenic and antimony so as to separate arsenic and antimony. Na_2S is used to precipate As_2S_3 which is then leached by using CuSO_4 solution and concentrated into crystallized As_2O_3. Antimony is recovered by using rising temperature distilling method to condense SbCl_3. This technique has many advantages-simple flowsheet and equipment, thorough separation between arsenic and antimony, low consumption and cost, high purity of products (above 99. 9%), and conspicuous social and economic benefit. |
