Patent number: 9945009Abstract: The present disclosure relates to processes for recovering rare earth elements from an aluminum-bearing material. The processes can comprise leaching the aluminum-bearing material with an acid so as to obtain a leachate comprising at least one aluminum ion, at least one iron ion, at least one rare earth element, and a solid, and separating the leachate from the solid. The processes can also comprise substantially selectively removing at least one of the at least one aluminum ion and the at least one iron ion from the leachate and optionally obtaining a precipitate. The processes can also comprise substantially selectively removing the at least one rare earth element from the leachate and/or the precipitate.Type: GrantFiled: January 22, 2016Date of Patent: April 17, 2018Assignee: ORBITE TECHNOLOGIES INC.Inventors: Richard Boudreault, Joël Fournier, Raymond Simoneau, Maria Cristina Garcia, Heinz Krivanec, Denis Primeau, Carsten Dittrich

Publication number: 20150104361Abstract: There are provided processes for recovering at least one rare earth element. Such processes comprise obtaining an acidic composition comprising (i) at least one rare earth element and optionally at least one rare metal; and reacting the composition with a precipitating agent so as to substantially selectively precipitate a first rare earth element and optionally a first rare metal. For example, various rare earth elements (such as scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, etc) and various rare metals (such as indium, zirconium, lithium, gallium, etc.) can be extracted by using such processes.Type: ApplicationFiled: March 13, 2013Publication date: April 16, 2015Inventors: Richard Boudreault, Denis Primeau, Heinz Krivanec, Carsten Dittrich, Marie-Maxime Labrecque-Gilbert

Patent number: 5036037Abstract: Process for producing catalysts for use within hydrogenation, oxidation, dehydration or dehydrogenation processes comprising oxides, in pure or mixed form, or being applied as mixed crystal systems, made of nickel, cobalt and molybdenum, vanadium, tungsten, titanium and chromium, starting with their corresponding aqueous solutions of their respective chlorides, fluorides or nitrates, which afterwards are processed within a pyrohydrolysis plant to gain the oxide powders, of typical specific surfaces areas of 1 to 100 m.sup.2 /g, agglomerate sizes of 1 to 500 microns and mean particle sizes of 20 to 30 microns. The corresponding anions of these salt solutions are transformed during pyrohydrolysis into their respective acids, which can be regained by absorptive means and which thereafter can be returned to a chemical dissolving process to make the salts and solutions for the pyrohydrolysis, which means an economic advantage.Type: GrantFiled: May 4, 1990Date of Patent: July 30, 1991Assignee: Maschinenfabrik Andritz AktiengesellschaftInventors: Wolfgang Kladnig, Heinz Krivanec
