由贵州工学院承担,柳州市有色冶炼总厂协作的贵州省“七·五”科技攻关项目“锑精矿软锰矿同时常压浸出Zn-MnO_2同时电解”半工业试验已经按期完成,并于一九八七年八月十一日在柳州市通过省级鉴定。专家们的鉴定意见认为:该流程设计思想新颖,功妙地将传统的湿法炼锌工艺和电解法制取二氧化锰工艺有机地结合起来,取消了各自的焙烧工序,同时制取电解锌和二氧化锰并可回收元素硫。明显地减少了对环
By the Guizhou Institute of Technology, Liuzhou Nonferrous Metals Smelting Plant cooperation in Guizhou Province, “Seventh Five-Year” scientific and technological project “antimony concentrate pyrolusite simultaneous atmospheric leaching Zn-MnO2 while electrolysis” semi-industrial test has been completed on schedule, and in a August 11, 1987 passed the provincial appraisal in Liuzhou. Experts believe that the identification of the design process, the flow of innovative ideas, a clever way to the traditional wet zinc smelting process and the electrolytic manganese dioxide process organically combine to cancel their roasting process, while the preparation of electrolytic zinc and Manganese dioxide and elemental sulfur can be recovered. Clearly reducing the ring
