The manufacture method disclosed herein includes: a preparation step of preparing a recovery object containing lithium and a first metal element; a chlorination heating step of heating the recovery object together with a metal chloride to produce LiCl; and a water dissolution step of immersing the recovery object after the chlorination heating step in water to dissolve LiCl in water to obtain a Li solution. In the manufacture method disclosed herein, a heating temperature in the chlorination heating step is 1000 C. or lower, and the metal chloride contains a second metal element that is more easily chlorinated than the first metal element in the recovered object and more hardly chlorinated than lithium in the chlorination heating step. Thereby, Li can be easily recovered from the recovery object at a low temperature of 1000 C. or lower.

A method for recovering metals, such as noble metals or copper, from secondary materials and other materials having organic constituents, wherein the organic components are extracted from the secondary materials and other material by thermal treatment in a process chamber and the secondary materials and other materials having organic constituents are prepared for the recovery process.

The cost of precious metals, such as gold, makes recovery or recycling of these materials economically viable and desirable. Disclosed herein is a method of recovering gold from waste sources thereof, in particular waste electrical goods. Also disclosed herein is an apparatus for recovering gold from said waste sources. In particular, disclosed herein is a method and apparatus in which gold leaching chlorine gas is generated externally to a reactor vessel and subsequently pumped into the reactor vessel comprising the waste gold materials.

Removing metal from metal-carbon material includes contacting the metal-carbon material with hydrogen chloride, thereby yielding a metal chloride in the gas phase and a solid product comprising carbon. The metal-carbon material and the solid product may both contain elemental carbon. A concentration of metal in the solid product is typically less than 1 wt %.

The present disclosure provides an apparatus for a chlorination method to recycle metal elements in lithium batteries.

The present invention discloses a method for recovering rare earth particulate material from an assembly comprising a rare earth magnet and comprises the steps of exposing the assembly to hydrogen gas to effect hydrogen decrepitation of the rare earth magnet to produce a rare earth particulate material, and separating the rare earth particulate material from the rest of the assembly. The invention also resides in an apparatus for separating rare earth particulate material from an assembly comprising a rare earth magnet. The apparatus comprises a reaction vessel having an opening which can be closed to form a gas-tight seal, a separator for separating the rare earth particulate material from the assembly, and a collector for collecting the rare earth particulate material. The reaction vessel is connected to a vacuum pump and a gas control system, and the gas control system controls the supply of hydrogen gas to the reaction vessel.

A method of isolating .sup.99Mo produced using a (n,) reaction according to example embodiments may include vaporizing a source compound containing .sup.98Mo and .sup.99Mo. The vaporized source compound may be ionized to form ions containing .sup.98Mo and .sup.99Mo. The ions may be separated to isolate the ions containing .sup.99Mo. The isolated ions containing .sup.99Mo may be collected with a collector. Accordingly, the isolated .sup.99Mo may have a relatively high specific radioactivity and, in turn, may be used to produce the diagnostic radioisotope, .sup.99mTc, through radioactive decay.

A method of producing a neodymium metal can include mixing a dissolution agent comprising magnesium with a neodymium-containing feedstock. The dissolution agent and the neodymium-containing feedstock can be heated to an elevated temperature above a melting temperature of the dissolution agent to form a neodymium-magnesium alloy. The neodymium-magnesium alloy can be exposed to hydrogen gas to convert neodymium in the alloy to a neodymium hydride. The neodymium hydride can be separated from the magnesium in the alloy. The neodymium can be optionally dehydrogenated to yield a purified neodymium product.

Disclosed herein are aspects of a method for recovering one or more metals from a feed comprising metal alloys, intermetallic compounds or a combination thereof. In certain aspects, the method can recover one or more metals of interest from waste streams comprising one or more permanent magnets, one or more lithium-ion battery anodes, or a combination thereof.

Provided is a method for recovering valuable metals from a positive electrode of waste lithium iron phosphate. The method includes: subjecting a waste lithium iron phosphate battery to discharging and disassembly; subjecting a lithium iron phosphate positive plate obtained by the disassembly to breaking, followed by high temperature treatment; uniformly mixing a product obtained by the high temperature treatment with a carbon material, and roasting a mixture in a high-purity Cl.sub.2 atmosphere; subjecting a gas phase product obtained by the roasting to fractional quenching and condensation to recover ferric chloride and aluminum chloride separately; and subjecting a solid phase product obtained by the roasting to water leaching and filtration to obtain a lithium chloride aqueous solution, and then adding sodium carbonate to precipitate lithium carbonate. As a one-step carbothermal chlorination method is adopted in combination with a two-stage quenching and condensation process in the present invention, the use of acidic solutions during recovery of valuable metals from the lithium iron phosphate positive electrode can be avoided, and the use of large amounts of alkaline solutions or extraction agents to separate and recover chlorides step by step is also not required. The method of the present invention has the advantages of a high metal recovery rate, a low comprehensive cost and good economic benefits, social benefits and environmental protection benefits.
