Patent number: 10174402Abstract: There are provided processes for preparing alumina. These processes can comprise leaching an aluminum-containing material with HCl so as to obtain a leachate comprising aluminum ions and a solid, and separating said solid from said leachate; reacting said leachate with HCl so as to obtain a liquid and a precipitate comprising said aluminum ions in the form of AlCl3, and separating said precipitate from said liquid; and heating said precipitate under conditions effective for converting AlCl3 into Al2O3 and optionally recovering gaseous HCl so-produced. These processes can also be used for preparing various other products such as hematite, MgO, silica and oxides of various metals, sulphates and chlorides of various metals, as well as rare earth elements, rare metals and aluminum.Type: GrantFiled: June 29, 2016Date of Patent: January 8, 2019Assignee: ORBITE TECHNOLOGIES INC.Inventors: Richard Boudreault, Joël Fournier, Denis Primeau, Marie-Maxime Labrecque-Gilbert

Publication number: 20160265082Abstract: The disclosed processes can be effective for treating various materials comprising several different metals. These materials can be leached with HCl for obtaining a leachate and a solid. Then, they can be separated from one another and a first metal can be isolated from the leachate. Then, a second metal can further be isolated from the leachate. The first and second metals can each be substantially selectively isolated from the leachate. This can be done by controlling the temperature of the leachate, adjusting pH, further reacting the leachate with HCl, etc. The metals that can be recovered in the form of metal chlorides can eventually be converted into the corresponding metal oxides, thereby allowing for recovering HCl. The various metals can be chosen from aluminum, iron, zinc, copper, gold, silver, molybdenum, cobalt, magnesium, lithium, manganese, nickel, palladium, platinum, thorium, phosphorus, uranium, titanium, rare earth element and rare metals.Type: ApplicationFiled: May 24, 2016Publication date: September 15, 2016Inventors: Richard BOUDREAULT, Denis PRIMEAU, Marie-Maxime LABRECQUE-GILBERT, Hubert DUMONT
