离子交换法除硫酸锰溶液中钴镍的中试研究
|
摘要
通过离子交换工艺,去除电解锰工业硫酸锰溶液中的钴镍离子并进行富集。采用6%～10%稀硫酸作为解吸剂,30～50 g/L氨水作为离子交换树脂转型剂,可以将硫酸锰溶液中钴镍离子含量降低到3 mg/L以下,解吸液中钴镍离子含量分别富集了24. 5倍、25. 1倍。离子交换树脂在吸附钴镍离子的同时,对锌铜离子也具有良好的吸附效果,锌铜离子的含量能降低到3 mg/L、1 mg/L以下,有利于硫酸锰溶液的同步净化。
Through the ion exchange technology,the process of removing and enriching cobalt and nickel ions in manganese sulfate solution was studied in electrolytic manganese industry. The 6% ～ 10% dilute sulfuric acid was used as desorption agent,the 30 ～ 50 g/L ammonia water was used as transformation agent. The content of cobalt and nickel ions in manganese sulfate solution could be reduced to below 3 mg/L,and the contents of cobalt and nickel in desorption solution were enriched 24. 5 times and 25. 1 times. Ion exchange resin also had good adsorption effect on zinc and copper ions while adsorbing cobalt and nickel ions,and the content of zinc and copper ions could be reduced to below 3 mg/L and 1 mg/L,which was conducive to the simultaneous purification of manganese sulfate solution.
