Chemistry Of Inorganic Compounds > Treating Mixture To Obtain Metal Containing Compound > Group Iiia Metal Or Beryllium (al, Ga, In, Tl, Or Be) > Forming Compound Containing Plural Metals > Alkali Metal Aluminate > From Bauxite From BauxiteFrom Bauxite patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.07/26/07 - 20070172405 - Composition and method for improved aluminum hydroxide production An improved method and composition for producing aluminum hydroxide crystals from precipitation liquor, involves the addition of an emulsified crystal growth modifier comprising a C8-C10 fatty acid, precursors, salts or blends thereof. The emulsified crystal growth modifier also facilitates an upward shift in particle size distribution of aluminum hydroxide and ... 04/12/07 - 20070081932 - Composition and method for improved aluminum hydroxide production. An improved method and composition for producing aluminum hydroxide crystals in a Bayer process pregnant liquor, involve the addition of an emulsified crystallization modifier comprising a C8-C10 fatty acid, precursors, salts or blends thereof. The alkyl chain of the fatty acid crystallization modifier is free of functional groups. The modifier ... 12/28/06 - 20060292050 - Composition and method for improved aluminum hydroxide production An improved method and composition for producing aluminum hydroxide crystals in a Bayer process pregnant liquor, involve the addition of a crystallization modifier comprising a C8-C10 fatty acid, precursors, salts or blends thereof. The alkyl chain of the fatty acid crystallization modifier is free of functional groups. The modifier yields ... 03/09/06 - 20060051268 - Method for attacking bauxite enhancing filterability of sludge in attack output Process for the treatment of bauxite (10) by alkaline digestion, typically using the Bayer process in order to obtain alumina hydrate, characterized in that ground bauxite (11, 15) is added directly into an alkaline solution (21a) that is drawn off and that will be reinserted into the Bayer aluminate liquor ... 10/27/05 - 20050238555 - Gas regulator A gas regulator includes a housing and a pressure regulator positioned within the housing along a first axis for controlling the pressure of gas received from a pressurized source. A flow meter controls the flow rate of the gas received from the pressure regulator. The flow meter is positioned relative ... 06/09/05 - 20050123460 - Solubilisation of carbonates by recycling condensates during digestion of monohydrate bauxites under pressure A method for the production of aluminum from bauxites containing aluminum monohydate of the diaspore or boehmite type which may contain more than 1.5% by weight of calcium carbonates. The ore is digested by the following steps: a1) a suspension, produced from the milled bauxite ore and the concentrated aluminate ... ### FreshPatents.com Support |
