  • Method of producing non-pyrophoric metallic iron
    Patent number: 8202345
    Abstract: A method for producing a substantially metallic iron-containing product from iron oxide. The metallic iron produced according to the invention is non-pyrophoric and may be safely shipped and handled without additional process steps. The method of the invention is simple, economical, and produces high quality metallic product which may be used as a feed for Electric Arc Furnace (EAF), Blast Furnaces and Cupolas among other applications.

  • Thermal reclamation method for the recovery of metals from air bag inflators
    Patent number: 5294244
    Abstract: A method of recovering an aluminum alloy and a stainless steel alloy from an air bag inflator 10 that has aluminum alloy parts, including an aluminum alloy housing 12 and non-aluminum alloy parts, including a non-aluminum gas filter 18. The non-aluminum parts have a higher melting temperature than the aluminum alloy parts of the air bag inflator 10. The method comprises heating the air bag inflator 10 in the range of the melting temperature of aluminum and then recovering the aluminum alloy which is not contaminated with the material of the higher melting temperature parts. After the aluminum alloy has melted from the air bag inflator 10, the non-aluminum parts are heated to a higher temperature to melt any stainless steel alloy from the non-aluminum parts. The stainless steel alloy is recovered as a high purity stainless steel alloy end product.
