    摘要: The present disclosure relates generally to systems and methods for recycling lead-acid batteries, and more specifically, relates to purifying and recycling the lead content from lead-acid batteries. A system includes a reactor that receives and mixes a lead-bearing material waste, a carboxylate source, and a recycled liquid component to form a leaching mixture yielding a lead salt precipitate. The system also includes a phase separation device coupled to the reactor, wherein the phase separation device isolates the lead salt precipitate from a liquid component of the leaching mixture. The system further includes a closed-loop liquid recycling system coupled to the phase separation device and to the reactor, wherein the closed-loop liquid recycling system receives the liquid component isolated by the phase separation device and recycles a substantial portion of the received liquid component back to the reactor as the recycled liquid component.

    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.

    摘要: In the method, the spent stripper solution for tin or a tin mixture is treated to precipitate dissolved or suspended metal compounds. On the one hand chemicals for reuse, and on the other hand metals such as copper, tin, lead and/or iron are recovered from the waste water streams. Efficiency of the precipitation is improved by heating of the stripping solution at elevated temperatures, and by the addition of a precipitating reagent. Once the precipitate is removed, the remaining liquid may be reused, typically as an admixture with a fresh solution. In the production method of a regenerated stripping solution for tin comprising at least one inorganic acid, ferric ions, at least one organic acid, and at least one organic additive, the stripping solution is heated at elevated temperatures, precipitating reagent is added, precipitated matter is separated and removed, and one or some of the acids or additives mentioned are added for the recovery of the desired tin stripping capacity.
