    Abstract: Method of treating rare earth metal-bearing scrap, waste or other material (e.g. Nd--Fe--B or Dy--Tb--Fe scrap) to recover the rare earth metal comprising melting the rare earth metal-bearing material, melting a Group IIA metal extractant, such as Mg, Ca, or Ba, in which the rare earth is soluble in the molten state, and contacting the melted material and melted extractant at a temperature and for a time effective to extract the rare earth from the melted material into the melted extractant. The rare earth metal is separated from the extractant metal by vacuum sublimation or distillation.

    Abstract: A method of applying a Cr-bearing layer to a substrate, comprises introducing an organometallic compound, in vapor or solid powder form entrained in a carrier gas to a plasma of an inductively coupled plasma torch or device to thermally decompose the organometallic compound and contacting the plasma and the substrate to be coated so as to deposit the Cr-bearing layer on the substrate. A metallic Cr, Cr alloy or Cr compound such as chromium oxide, nitride and carbide can be provided on the substrate. Typically, the organometallic compound is introduced to an inductively coupled plasma torch that is disposed in ambient air so to thermally decompose the organometallic compound in the plasma. The plasma is directed at the substrate to deposit the Cr-bearing layer or coating on the substrate.

    Abstract: Materials in battery and electrochemical cells are separated in a form suitable for recycling by employing froth flotation techniques. Bulk materials, such as casings, are removed from converted battery scrap and the resultant pulp is subjected to froth flotation. Froth flotation agents, including frothers, collectors and/or depressants, are used to manipulate the hydrophilic and hydrophobic nature of the materials in the scrap. Hydrophobic materials are entrained in the air bubbles of the froth and float out of the froth flotation vessel while those that are hydrophilic remain in the vessel, thereby separating battery grid materials without resort to pyrometallurgical, energy intensive or other environmentally undesirable processes.
