中文摘要: 以Na2S为沉淀剂,采用硫化沉淀法从钴冰镍三段浸出液中回收其中的钴、镍等有价金属。通过单因素试验,考察了Na2S的加入量、酸度(pH)、反应温度和时间等因素对浸出液中铁、镍、钴沉淀率的影响。结果表明,适宜工艺条件为Na2S的过量系数3.0,pH=3.0~3.5,反应温度60 ℃,反应时间2 h,Co、Ni、Fe的沉淀率分别为~99%、~98%、~90%。
Abstract:Cobalt, nickel, and other valuable metals were recovered from cobalt-nickel matte three-stage leaching lixivium with precipitation process with Na2S as precipitant. The effects of dosages of Na2S, acidity (pH), temperature and time on precipitation rates of Fe, Ni, Co with single factor experiment. The results show that the precipitation rates of Co, Ni, Fe are ~99%, ~98%, ~90%, respectively, under the following optimum conditions including Na2S excessive coefficient of 3.0, pH of 3.0~3.5, temperature of 60 ℃, and time of 2 h.
