    Abstract: The present disclosure relates to systems and methods by which lead from spent lead-acid batteries may be extracted, purified, and used in the construction of new lead-acid batteries. A method includes forming a first mixture in a first vessel, wherein the first mixture includes a lead-bearing material and a carboxylate source, which react to precipitate lead salt particles. The method includes separating a portion of the first mixture from a remainder of the first mixture, wherein the portion includes lead salt particles having specific densities below a specific density threshold value and/or having particle sizes below a particle size threshold value. The method includes forming a second mixture in a second vessel, wherein the second mixture includes the lead salt particles from the separated portion of the first mixture. The method further includes separating the lead salt particles of the second mixture from a liquid component of the second mixture.

    Abstract: The present disclosure relates generally to recycling lead-acid batteries, and more specifically, relates to purifying and recycling the lead content from lead-acid batteries. A lead recovery system includes a first reactor configured to receive and mix a lead-bearing material and a first carboxylate source to yield a first mixture, wherein the first mixture includes a first lead carboxylate that is dissolved in a liquid component of the first mixture. The system includes a second reactor configured to receive and mix the liquid component of the first mixture and a second carboxylate source to yield a second mixture, wherein the second mixture includes solid particles of a second lead carboxylate. The system includes a third reactor configured to receive and mix the solid particles of the second lead carboxylate and a hydroxide solution to yield a third mixture, wherein the third mixture includes solid particles of lead oxide.

    Abstract: The present disclosure relates to methods by which lead from spent lead-acid batteries may be extracted, purified, and used in the construction of new lead-acid batteries. A method includes: (A) forming a mixture including a carboxylate source and a lead-bearing material; (B) generating a first lead salt precipitate in the mixture as the carboxylate source reacts with the lead-bearing material; (C) increasing the pH of the mixture to dissolve the first lead salt precipitate; (D) isolating a liquid component of the mixture from one or more insoluble components of the mixture; (E) decreasing the pH of the liquid component of the mixture to generate a second lead salt precipitate; and (F) isolating the second lead salt precipitate from the liquid component of the mixture. Thereafter, the isolated lead salt precipitate may be converted to leady oxide for use in the manufacture of new lead-acid batteries.
