第1の硫化物沈殿剤(14)を用いてpH2~4で第1の浸出溶液(2)からNiおよびCoを沈殿させ、それによって分離したMn含有水相(6)およびNiおよびCo含有固相(7)を得る、第1の沈殿ステップ(P1)をさらに備える。
第1の硫化物沈殿剤(14)は、好ましくはH2Sである。
第2の硫化物沈殿剤(15)を用いてpH0.5~1.5で第2の浸出溶液(4)からCuを沈殿させ、それによって分離した金属含有水相(8)およびCu含有固相(9)を得る第2の沈殿ステップ(P2)と、
第1の酸性水溶液(11)として使用するために金属含有水相(8)の大部分を第1の浸出ステップ(L1)に再循環させるステップと、をさらに備える。
第2の硫化物沈殿剤(15)は、好ましくはH2Sおよび/または単体硫黄およびSO2の混合物である。
加熱および/または水の蒸発によってMn含有水相(6)からMnを結晶化させ、それによって分離したMn含有固体を得る結晶化ステップと、
