我厂副产的焊锡,过去用氯盐电解法电解,虽能有效地使铅锡分离,直接获得精锡产品,但此法存在着一系列的缺点。如流程长,金属回收率低;设备庞大,厂房占地多,基建投资多,时间长;原材料消耗大,能耗大,成本高;尤其是阳极泥处理困难,劳动强度大,条件差,污染环境严重等。为 I produced by-product of the solder, the past electrolysis using chloride electrolysis, although the tin can be effectively separated, direct access to refined tin products, but this method has a series of shortcomings. Such as long process, low metal recovery; large equipment, plant covers an area of ​​more infrastructure investment, a long time; raw material consumption, energy consumption, high cost; especially anode mud handling difficulties, labor intensity, poor conditions, pollution The environment is serious and so on. for
