  • Hydrometallurgical Processes For Battery Recycling
    Publication number: 20230279520
    Abstract: A method of recovering lead, antimony tin from lead acid batteries, lead bearing scrap and other lead bearing materials which includes smelting lead bearing materials in a reverb furnace to recover metallic lead; leaching the resultant slag produced in the reverb furnace with ammonium chloride (NH4Cl) to produce a slurry; precipitating antimony from the slurry with ferric chloride (FeCl3); performing a solid-liquid separation of the slag away from the resulting pregnant leach solution; precipitating lead carbonate (PbCO3) from the pregnant leach solution with carbon dioxide (CO2); recovering the precipitated lead carbonate (PbCO3) through solid-liquid separation; and processing the precipitated lead carbonate (PbCO3) in a reverb furnace to recover metallic lead.

  • Methods and systems for leaching a metal-bearing ore for the recovery of a metal value
    Patent number: 8491701
    Abstract: A system and method for recovering a metal value from a metal-bearing ore material are provided. A metal-bearing ore can be mixed with certain substances and to form an agglomerated ore. In an intermediate state, between agglomeration and heap formation, bacteria can be added to the metal-bearing ore material to produce an augmented ore. The augmented ore can then be formed into a heap.
    Type: Grant
    Filed: January 24, 2012
    Date of Patent: July 23, 2013
    Assignee: Freeport-McMoran Corporation
    Inventors: John Lawrence Uhrie, Gabe Bowman, Cristian Alejandro Caro Matus, Percy Mayta, Scott Hoenecke, Manuel Chavez
