摘要
采用氨络合法从铁—镍废液中回收镍,讨论了温度、中和时间、搅拌速度对反应的影响。该工艺提高了镍的回收率和产品纯度,在最佳工艺条件下,镍回收率大于90%,纯度大于40%。
The technology route and the condition of recovery of nickel from Ni - Fe waste liquid by ammonia complexation are studied. The recovery ratio of nickel and product purity is increased. Under the optimal conditions, the recovery ratio of nickel is over 90% ,the purity of nickel is over 40%.
