我厂在以镍磷铁为原料生产电解镍的过程中,过去是采用化学沉淀法净化溶液,产出大量固态残渣,因而金属回收率低,劳动条件差,工艺过程也比较复杂。为了改革这一不合理的流程,在有关单位的协助下,采用了N-235萃取净液法。几年来,在毛主席革命路线指引下,经过反复实践,证明改革 In the process of producing Ni-Fe from Ni-Fe-Fe, in the past, the chemical precipitation method was used to purify the solution to produce a large amount of solid residues, so the metal recovery rate was low, the working conditions were poor, and the process was complicated. In order to reform this unreasonable process, with the help of the relevant units, the N-235 extraction method was adopted. In the past few years, under the guidance of Chairman Mao’s revolutionary line, through repeated practice, the reform proved
