一、简况我厂利用含镍工业废料生产电镍,在回收过程中,许多有价金属如铜等都以杂质形式除去。这样,价格昂贵的铜得不到回收利用,并污染环境。同时,在除铜过程中要耗费大量的化学药品。目前,由于富镍废料的减少,不得不大量采用贫镍料,铜含量明显增加。我厂镍阳极液含铜0.5～0.3g/1。经过多方面 First, the briefing I plant nickel-containing industrial waste production of nickel, in the recovery process, many valuable metals such as copper are removed as impurities. In this way, expensive copper can not be recycled and pollute the environment. At the same time, in the process of removing copper to spend a lot of chemicals. At present, due to the reduction of nickel-rich waste, a large amount of lean nickel materials have to be used, and the copper content has obviously increased. I plant nickel anolyte copper 0.5 ~ 0.3g / 1. After many aspects
