Title: Methods for liquid extraction of rare earth metals using ionic liquids

Abstract

A method for extracting a rare earth element from a rare earth-containing substance, the method comprising mixing the rare earth-containing substance with a protic ionic liquid, such as: wherein R1 is selected from hydrogen atom and hydrocarbon groups containing 1 to 6 carbon atoms; R2 and R3 are independently selected from hydrocarbon groups containing 1 to 12 carbon atoms; and X− is an anionic species; to produce a composition of the formula (RE)(amide)yXz at least partially dissolved in the protic ionic liquid, wherein RE is at least one rare earth element having an atomic number selected from 39, 57-71, and 90-103; y is 2-6; z is a number that charge balances the total positive charge of RE; and the amide is the conjugate base of the cationic portion of the protic ionic liquid of Formula (1) and has the following formula:

Recycling of rare earth metals from rare earth-transition metal alloy scrap by liquid metal extraction

Patent Ellis, Timothy W [Ames, IA]; Schmidt, Frederick A [Ames, IA]

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.

Method and apparatus using an active ionic liquid for algae biofuel harvest and extraction

Patent Salvo, Roberto Di; Reich, Alton; Dykes, Jr., H. Waite H.; ...

The invention relates to use of an active ionic liquid to dissolve algae cell walls. The ionic liquid is used to, in an energy efficient manner, dissolve and/or lyse an algae cell walls, which releases algae constituents used in the creation of energy, fuel, and/or cosmetic components. The ionic liquids include ionic salts having multiple charge centers, low, very low, and ultra low melting point ionic liquids, and combinations of ionic liquids. An algae treatment system is described, which processes wet algae in a lysing reactor, separates out algae constituent products, and optionally recovers the ionic liquid in an energymore » efficient manner. « less

Recovery of rare earth elements by liquid-liquid extraction from fresh water to hypersaline solutions

Patent Noack, Clinton W.; Karamalidis, Athanasios K.; Dzombak, David A.

The disclosure describes a method of extraction for optimal recovery of rare earth elements (REE). This includes the optimization of a liquid-liquid extraction technique for economic extraction of REE from chemically complex brines. Through the use of a model, operating conditions are altered to increase separation efficiency. The technique achieves >98% recovery of all rare earth elements in one fraction, while using small volumes of sample and reagents. The method of the present invention recovers REE from previously unexploited waste streams, without need for development of new process equipment and while keeping a small footprint because of the volumes involved.

Methods of forming metals using ionic liquids

Patent Baek, Donna L.; Fox, Robert V.; Lister, Tedd E.

A method of forming an elemental metal (e.g., a rare-earth element) includes forming a multicomponent solution comprising an ionic liquid, a secondary component, and a metal-containing compound. The multicomponent solution is contacted with at least a first electrode and a second electrode. A current is passed between the first electrode to the second electrode through the multicomponent solution. The metal-containing compound is reduced to deposit the elemental metal therefrom on the first electrode.
