工人沈宝生、姚干昌破除迷信,刻苦钻研,提炼碳酸镍八道工序改一道,效率增加10倍,质量大大提高,成本大大降低,打破了过去认为硫化氢除锌的提炼方法不能用于工业生产的说法。碳酸镍是从铜的废液中提炼出来,再加工制造金属镍的,电解铜废液中,含有铁、铜锌、镍等物质,要从中提炼出镍来,必须除去铜、铁、锌等杂质。在提炼过程中,铜、铁两项较易摒除,而除去锌最为困难。过去,这个
Workers Shen Baosheng, Yao Qianchang to get rid of superstitions, assiduously research refined nickel carbonate eight processes to change, the efficiency increased 10 times, the quality is greatly improved, the cost is greatly reduced, breaking the past that the method of removing hydrogen sulfide, zinc can not be used in industrial production . Nickel carbonate is extracted from the copper waste liquid, and then processing and manufacturing nickel metal, electrolytic copper waste, containing iron, copper, zinc, nickel and other substances, to extract nickel from it, you must remove copper, iron, zinc, etc. Impurities. In the refining process, copper, iron two easier to exclude, and remove the most difficult zinc. In the past, this
