  • Recovery of high purity PbO
    Patent number: 7785561
    Abstract: A process for producing high purity lead oxide from impure lead compounds particularly from waste lead battery paste which includes an oxidation-reduction step. The process results in a reduction of impure lead compounds to the +2 valence state and metal particle contaminants are oxidized to the +2 state.

  • Process for recovering lead oxides from exhausted batteries
    Patent number: 7507496
    Abstract: A process for recovering lead oxides from the spent paste of exhausted lead acid batteries. The process provides heating the spent paste with an alkali hydroxide solution at elevated temperatures prior to calcinations. Calcination is at various temperatures so that either lead mono-oxide, lead dioxide or red lead is obtained as the principal product. There is also provided the use of the lead oxide to prepare the paste for positive and negative electrodes or other lead compounds.
