Abstract: The present relates to a process of shredding a lithium battery. The lithium battery is shredded and quenched with a shredding liquid in a shredding compartment to safely discharge the batteries and producing shredded battery residues and a liquid comprising organic compounds and lithium compound. At least a portion of the liquid is separated from the shredded battery residues to obtain a separated liquid containing a low flash point solvent and a high flashpoint solvent. A recycled shredding liquid is produced from the separated liquid by removing at least a portion of the low flash point solvent and/or increasing the concentration of the high flashpoint solvent in the recycled shredding liquid to increase a flash point of the recycled shredding liquid compared to the shredding liquid in the shredding compartment. The recycled shredding liquid is fed to the shredding compartment to replace at least a portion of the shredding liquid.

Abstract: There is provided a process for purifying aluminum ions comprising: reacting an aluminum-containing material with an acid so as to obtain a composition comprising aluminum ions; precipitating said aluminum ions in the form of AlCl3; optionally converting AlCl3 into Al(OH)3; and heating said AlCl3 or said Al(OH)3 under conditions effective for converting AlCl3 or Al(OH)3 into Al2O3 and optionally recovering gaseous HCl so-produced. Aluminum ions so purified are thus useful for preparing various types of alumina.

Abstract: There are provided processes for converting alumina into ?-Al2O3 or transition alumina that comprise heating the alumina at a temperature of about 900° C. to about 1200° C. in the presence of steam and optionally at least one gas under conditions suitable to obtain the ?-Al2O3 or transition alumina. For example, the alumina can comprise a transition alumina (such as ?-Al2O3), an amorphous alumina or a mixture thereof.

Abstract: There are provided processes for purifying aluminum ions. Such processes comprise precipitating the aluminum ions under the form of Al(OH)3 at a first pH range; converting Al(OH)3 into AlCl3 by reacting Al(OH)3 with HCl and precipitating said AlCl3; and heating the AlCl3 under conditions effective for converting AlCl3 into Al2O3 and optionally recovering gaseous HCl so-produced. The processes can also comprise converting alumina into aluminum.

Abstract: There is provided a process for preparing alumina. The process comprise leaching an aluminum-containing material (for example an industrial waste product chosen from red mud, fly ashes and a mixture thereof), with HCl so as to obtain a leachate comprising aluminum ions and a solid, and separating the solid from the leachate. Then, the process comprises reacting the leachate with HCl so as to obtain a liquid and a precipitate comprising the aluminum ions in the form of AlCl3, and separating the precipitate from the liquid. Then, the precipitate is reacted with a base. Finally, the process comprises heating the precipitate under conditions effective for converting the precipitate into Al2O3.

Abstract: 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.

Abstract: The invention encompasses a process for granulating particles that produces homogeneous, free flowing, attrition resistant, uniform sized granules. When utilized with active pharmaceutical ingredients, such granules can be further processed into controlled released or taste-masked pharmaceutical formulations. Particularly, the process can be utilized to make an oral granule formulation of etoricoxib for treating pain and inflammation in patients that cannot swallow a tablet, such as young children and the elderly.

Abstract: The present invention encompasses a flavored and taste-masked pharmaceutical composition comprising a plurality of pharmaceutically acceptable cores, such as microspheres, said pharmaceutically acceptable cores comprising etoricoxib, wherein the pharmaceutically acceptable cores are coated with a flavored taste-masking coating solution in a convenient one-step process.
