摘要： A method of washing anode slime from lead-bismuth alloy electrolysis is disclosed, wherein a lead fluorosilicate solution with high concentration can be obtained by using the anode slime from lead-bismuth alloy electrolysis as raw material, which is characterized in that the method includes the following steps: (1) pretreating the anode slime, (2) primarily soaking the anode slime, (3) secondarily soaking the anode slime. A method of washing anode slime from lead-bismuth alloy electrolysis, and obtaining a soaking solution containing a lot of lead ions and fluorosilicic anions is provided. The soaking supernatant is added directly into the electrolyte-circulating system of lead-bismuth alloy electrolysis, which increases the utilization rate of lead ions and fluorosilicic anions, and improves the environment for smelting bismuth and silver, while reduces production cost for smelting lead, bismuth and silver. The method optimizes the process for the lead-bismuth alloy electrolysis, and solves the problem of “lean-lead” in the lead-bismuth alloy electrolysis.
