  • Process for the recovery of metals from used nickel/metal hydride batteries
    Patent number: 8246717
    Abstract: The present invention provides a process of recovering AB5 and/or AB2 as well as other metals from spent nickel metal hydride batteries from a slury by a series of separation steps utilizing the screening off of larger metal particles, removal of magnetizable small metal particles from a filter and then separating AB5 and/or AB2 by passing the filtrate through a froth flotation step to separate AB5 and/or AB2 from lighter small particles.

  • 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.

  • Method for the neutralization of hazardous materials
    Patent number: 5345033
    Abstract: A method for neutralizing hazardous materials wherein the material and if applicable, the device within which such material is contained, is first cooled to substantially sub-ambient temperatures. The material is then safely extractable from such device and exposed to the appropriate reactants in order to form benign products. Most of the hazards associated with accessing, handling, and reacting these materials are thereby eliminated and such is achieved in relatively economical manner.
