中文摘要: 在硫酸体系下对某含钴原料进行了还原浸出研究。考察硫酸用量、亚硫酸钠用量、浸出温度、聚丙烯酰胺用量对钴浸出率及过滤性能的影响。结果表明，对1 kg钴原料，在液固比5∶1、浸出温度60 ℃、浓硫酸400 mL、亚硫酸钠用量360 g、浸出终点pH 1.0~1.5的条件下，钴浸出率达到97%以上。加入20~40 mL聚丙烯酰胺可以改善浸出液的过滤性能。
Abstract:Cobalt-bearing raw materials were reduction leached in sulfuric acid system. The effects of dosage of sulfuric acid and sodium sulfite, leaching temperature, dosage of polyacrylamide on leaching rate of cobalt and the filtering performance were investigated. The results show that the leaching rate of cobalt is above 97% and the filtering performance is favorable under the optimum conditions including (for 1 kg raw materials) ratio of liquid to solid of 5∶1, leaching temperature of 60 ℃, dosage of concentrated sulfuric acid of 400 mL, dosage of sodium sulfite of 360 g, dosage of polyacrylamide of 20~40 mL, and pH value of terminal of 1.0~1.5.
