A rotary injector comprising an elongated shaft having a proximal end and a distal end, and an impeller at the distal end of the elongated shaft, the elongated shaft and the impeller being collectively rotatable during operation around an axis of the shaft, the rotary injector being hollow and having an internal supply conduit extending along the shaft and across the impeller, the supply conduit having an inlet at the proximal end of the shaft, a main portion extending from the inlet to a discharge portion, the discharge portion extending to an axial outlet, the discharge portion having a narrow end connecting the main portion of the supply conduit and a broader end at the axial outlet.

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.

Disclosed herein is a method of forming an alloy material for use in a wire. The method includes forming a master alloy containing lead and silver; and creating a molten wire alloy by combining the master alloy, additional lead, and a third material in a vessel. The method also includes flowing argon gas through and over the molten wire alloy. The method also includes drawing the molten alloy from the vessel through an actively cooled die, and solidifying the molten wire alloy to form a bar of wire alloy.

A method of processing an iron-rich rare earth bearing ore which includes the steps of smelting the ore to concentrate rare earth oxide minerals in the ore into a slag phase and extracting the rare earth oxide minerals from the slag.

A method for melting ferrous metals, non-ferrous metals, machining waste and scrap and steel, includes the following steps of providing a closed container made of a material that is compatible with a melting bath in which it is to be placed and is adapted to contain materials adapted to be used as corrective substances in the melting bath; introducing the corrective substances in the container so as to obtain a closed container which contains the corrective substances; inserting the closed container in the melting bath; and monitoring the melting of the container and the release of the corrective substances in the melting bath.

A method for continuous semisolid die casting. The method is achieved using an apparatus for continuous semisolid die casting. The apparatus includes: a first preparation device for producing a nucleating agent, a second preparation device for producing semisolid slurry, a semisolid die casting machine, and a central controller. The second preparation device includes a slurry generator. The method includes: controlling, by the central controller, the first preparation device to produce a solid nucleating agent, and delivering the solid nucleating agent to the slurry generator of the second preparation device; controlling, by the central controller, the second preparation device to produce semisolid slurry, and delivering the semisolid slurry to the semisolid die casting machine; and controlling, by the central controller, the semisolid die casting machine to perform semisolid die casting.

Systems, methods, and apparatus for treating a molten metal are provided. A metal treatment system, comprising: a wire feeding subsystem; and a cored wire; wherein the wire feeding subsystem feeds the cored wire into a metal bath at a controlled wire feed rate, and wherein the metal bath comprises a molten metal; wherein the cored wire comprises: a consumable outer sheath having a tubular cross section; and a core fill material coupled to an inner surface of the outer sheath, wherein the core fill material comprises a refining agent for refining the molten metal; and wherein the refining agent reacts with the molten metal, thereby causing an impurity to be removable from the metal bath.

A method of fluxing or degassing a molten metal residing as a bath in a furnace. The bath of molten metal includes a bath surface height and the method provides at least one rotating impeller in the molten metal bath to initiate a flow of the molten metal. The flow in the molten metal results in elevating a portion of the molten metal above the bath surface height where at least one of a fluxing agent and an inert gas is introduced into the elevated portion of the molten metal.

A method of processing an iron-rich rare earth bearing ore which includes the steps of smelting the ore to concentrate rare earth oxide minerals in the ore into a slag phase and extracting the rare earth oxide minerals from the slag.
