在铜矿浸出-溶剂萃取-电积工艺中,由于浸出富液含有较高的固体悬浮物,从而影响萃取和电积过程进行。曾采用逆流倾析、浓缩-砂滤、凝聚-过滤法处理含有固体悬浮物的浸出液,但效果都不好。Bateman公司采用阻塞床澄清器处理浸出液获得很好的结果。该澄清器已在很多冶炼厂中得到应用。这种澄清器得到的澄清液的固体含量低,设备处理量大,能在线回洗,机械结构简单,操作方便,投资和操作费用低。
In the copper leaching-solvent extraction-electrowinning process, the extraction and electrowinning processes are affected by the leaching of the rich liquid which contains a high amount of suspended solids. Had used countercurrent decantation, concentration - sand filtration, cohesion - filtration solution containing solid suspended solids leachate, but the effect is not good. Bateman’s treatment of the leachate with a blocking bed clarifier yielded good results. This clarifier has been used in many smelters. The clear liquid obtained by this clarifier has low solid content, large processing capacity and can be backwashed online. The mechanical structure is simple, the operation is convenient, and the investment and operation cost are low.
