    摘要： There is described a process completely performed in aqueous phase, which provides a heat etching of lead glass with aqueous solutions of strong alkali followed by an electrolytic treatment of the suspension so obtained, in order to recover metallic lead and obtain soluble silicates, separated from insoluble silicates, both lead-free. The process also provides for the production of pure silica, derived from the soluble silicates, and a possible use thereof to increase the ratio between silica and sodium oxide, which characterizes the specifications of the soluble silicates. The electrolysis for the recovery of metallic lead is implemented in a cell in which the polarity of the electrodes is periodically reversed, to obtain the detachment of the metallic lead deposited on the cathodes.

    摘要： 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.

    摘要： Wet process of low environmental impact recovers the lead content of an electrode slime and/or of lead minerals in the valuable form of high purity-lead carbonates that are convertible to highly pure lead oxide by heat treatment in oven at relatively low temperature, perfectly suited for making active electrode pastes of new batteries or other uses. The process basically comprises the following steps: a) adding sulphuric acid to a different acid leach suspension of the starting impure material for converting all dissolved lead compounds to insoluble lead sulphate; b) separating the solid phase constituted by lead sulphate and undissolved impurities from the acid leach solution; c) selectively dissolving lead sulphate contained in said separated solid phase in an aqueous solution of a lead solubilizing compound comprising preferably sodium acetate; d) separating the solution containing dissolved lead sulphate from the solid phase residue including undissolved impurities; e) adding to the separated solution of lead sulphate a carbonate of the same cation of said dissolving compound for forming insoluble lead carbonate and/or and lead oxycarbonate and a dissolved sulphate of the same cation; f) separating the precipitated carbonate and/or oxycarbonate of lead from the dissolving solution now containing also sulphate of the cation of said solubilizing compound.
