电化学提取锑的硫化-碱法工艺包括用返回的电解液从原料中浸出锑、碱式电解及电化学贫化部分返回电解液,然后将贫化液排到盐储存器中。当电流效率为72—74%时,排出贫化(盐漂洗)的返回电解液,可以使碱式电解中电解液的成分稳定。在阴极上锑的回收率95%,而随浸出废渣损失的锑为3.8—3.5%,随废电解液损失的锑为1.2～1.5%。在串联电
The sulfide-alkaline process for the electrochemical extraction of antimony involves the leaching of antimony from the feedstock with the returned electrolyte, the alkaline electrolysis and the electrochemically depleted portion back to the electrolyte, and the depleted liquid to the salt reservoir. When the current efficiency is 72-74%, the depleted (salt-rinsed) return electrolyte is discharged to stabilize the composition of the electrolyte during the basic electrolysis. The recovery rate of antimony on the cathode is 95%, while the loss of antimony with leaching residue is 3.8-3.5%, while the loss of antimony with waste electrolyte is 1.2-1.5%. In series electricity
