鈷鉄合金的硫酸浸出液成分,一般在下列范围內(克/升):Co 5～10,Fe 40～80,Cu 0.004～0.1,Mn 0.4～2,Ni 0.5～2。比重1.1～1.2。鈷鉄重量比为1:(8～10)。銅的含量由浸出过程中是否有效地采用了置換而定。其它杂质随鈷鉄成分而变化,有时含有少量鋅。浸出液的pH值可达5～6,由于含鉄量过大,一般的氧化除铁方法都不适用了。作者曾对以碱式硫酸鉄形式除去鉄的方法作过研究,但是氧化剂价格高。寻找在經济上更合理,同时鈷回收率和除鉄率等指标也高的方法是有必要的。上述成分的溶液在比重增高至1.2以上时,就会产生暗黄色結晶。結晶含鈷2％±,合鉄17％±,含
Cobalt 鉄 alloy sulfuric acid leachate composition, generally within the following range (g / liter): Co 5 ~ 10, Fe 40 ~ 80, Cu 0.004 ~ 0.1, Mn 0.4 ~ 2, Ni 0.5 ~ The proportion of 1.1 to 1.2. Cobalt 鉄 weight ratio of 1: (8 ~ 10). The copper content is determined by the effective replacement of the leaching process. Other impurities vary with the composition of cobalt,, sometimes containing a small amount of zinc. The leachate pH value of up to 5 to 6, due to containing too much, the general method of removing iron oxide are not applicable. The authors have done some research on the method of removing gallium from chrysanthemum sulfate, but the price of oxidants is high. Finding ways that are economically justified and indicators of cobalt recovery and removal rates are also high is necessary. The solution of the above composition increases in the specific gravity of 1.2 or more, it will produce dark yellow crystal. Crystallization containing cobalt 2% ±, 鉄 鉄 17% ±, containing
