摘要
以某低品位钴银矿浮选精矿为原料 ,在湿法提取冶金过程中先将砷固留在焙砂中 ,然后采用适宜的脱砷剂将其从浸出液中除去。用硫化法净化浸出液中的重金属离子 ,用萃取法分离镍、钴 ,最后用合格的含钴溶液制取草酸钴产品。而银存留于浸出渣中待回收。
This paper describes a hydrometallurgical process of a low-grade arsenic-bearing argetiferous cobalt flotation concentrate as a material. During the hydrometallurgical extraction, the arsenic is firstly fixed in calcines, and then arsenic removal from leaching liquor is achieved with a suitable dearsenifying agent. Purification of leaching liquor for removing heavy metal ions is performed by a method of sulphidization, and extraction separation of nickel and cobalt is performed by a method of extraction. Finally, the product of cobalt oxalate from qualified cobaltic solution is obtained. Silver is remained in the leaching residue.
