会泽铅锌矿湿法处理含铅、锌、锗烟尘。用丹宁沉锗后的硫酸锌溶液经氧化、中和、进一步净化后电解得到电锌。1977年前,采用高锰酸钾氧化,石灰乳中和、氢氧化铁共沉法除砷、锑。为了脱除砷、锑,生产中有一个制备硫酸亚铁的工序,来满足Fe/As≮2.5的要求。氢氧化铁共沉法除砷、锑,消耗昂贵的高锰酸钾,生产硫酸亚铁劳动条件差,原始溶液含砷超过800毫克/升必须进行两次中和且除砷
Huize Pb-Zn wet processing lead, zinc, germanium dust. After tannin Shen germanium sulfate solution by oxidation, neutralization, further purification and electrolysis to obtain zinc. Before 1977, the use of potassium permanganate oxidation, milk and lime, iron hydroxide co-precipitation arsenic, antimony. In order to remove arsenic, antimony, there is a production process of ferrous sulfate to meet the requirements of Fe / As≮2.5. Iron hydroxide coprecipitation In addition to arsenic and antimony, which consume expensive potassium permanganate, the production of ferrous sulphate is poor working conditions. The original solution containing arsenic over 800 mg / l must be neutralized and arsenic removed twice
