  • Process for obtaining highly pure litharge from lead acid battery paste
    Patent number: 8980203
    Abstract: The present invention relates to the recovery of high purity litharge from spent lead acid battery paste at a low temperature which does not produce sulfur dioxide. In the process lead acetate or other lead salt is produced which is converted to high purity litharge by precipitation with a base.
    Type: Grant
    Filed: May 24, 2013
    Date of Patent: March 17, 2015
    Assignee: Retriev Technologies Incorporated
    Inventors: W. Novis Smith, Steven Kinsbursky
  • Recovery of high purity lead oxide from lead acid battery paste
    Patent number: 8715615
    Abstract: The invention relates to the low temperature recovery of lead oxide (PbO) from lead acid battery paste through the preparation of lead carboxylate from the battery paste and the conversion of the lead carboxylate to PbO.
    Type: Grant

  • Recovery of high purity lead oxide from lead acid battery paste
    Patent number: 8323595
    Abstract: There is provided a process for recovering high purity litharge PbO from spent lead acid battery paste at low temperatures and the further preparation of highly pure lead oxides and Pb(OH)2.
    Type: Grant
    Filed: September 3, 2011
    Date of Patent: December 4, 2012

    Inventors: W. Novis Smith, Steven A. Kinsbursky
  • 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.
    Type: Grant

  • 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.
