Recovering heavy rare earth metals from magnet scrap

Номер: US20160362766A1
Автор: Ryan T. Ott, Ralph W. McCallum, Lawrence L. Jones, OTT RYAN T, MCCALLUM RALPH W, JONES LAWRENCE L, Ott Ryan T., McCallum Ralph W., Jones Lawrence L.
Принадлежит: Iowa State University Research Foundation, Inc.

A method of treating rare earth metal-bearing permanent magnet scrap, waste or other material in a manner to recover the heavy rare earth metal content separately from the light rare earth metal content. The heavy rare earth metal content can be recovered either as a heavy rare earth metal-enriched iron based alloy or as a heavy rare earth metal based alloy.

Recovering rare earth metals from magnet scrap

Номер: US20170016088A1

A method is provided for treating a rare earth metal-bearing scrap material by melting an extractant selected from the group consisting of bismuth (Bi) and lead (Pb) and contacting the melted extractant and the scrap material at a temperature and time to recover at least one of the light rare earth metal content and the heavy rare earth metal content as a metallic extractant alloy, which can be subjected to vacuum distillation or sublimation to recover the rare earth metal(s). The method can be practiced to recover the light rare earth metal content and the heavy rare earth metal content concurrently in a one-step process or separately and sequentially in a two-step process.

A product includes an aluminum alloy having an anodized layer. The alloy has a bulk composition including at least 1 wt. % of one or more rare earth elements (REEs). A product includes microstructures extending across a boundary defined between an anodized layer and an unoxidized alloy. Each microstructure includes an intermetallic phase transitioning to an oxidized intermetallic phase across the boundary. A product includes an anodized layer where up to 90% of a thickness of the layer includes voids resulting at least in part from dissolution of a rare earth element oxidized intermetallic phase. The voids are in a morphology of the dissolved oxidized intermetallic phase.

A method for fabrication of an anisotropic magnet comprises placing magnet alloy feedstock particles in a deformable metallic container and thermomechanically working the filled container in a manner to elongate the filled container and reduce its cross-sectional area to consolidate the magnet alloy particles to an elongated shape and impart a preferential grain texture to the consolidated, elongated shape. The consolidated, elongated shape is machined to a near-final magnet shape that has a smaller dimension such as magnet length and that includes a metallic tubular skin thereon.
