| 7179438 | Methods and apparatus for recovering gypsum and magnesium hydroxide The present invention provides methods and apparatus for treating flue gas containing sulfur dioxide using a scrubber, and more particularly relates to recovering gypsum and magnesium hydroxide products from the scrubber blowdown. The gypsum and magnesium hydroxide ... | 02/20/2007 |
| 6099814 | Method for processing acid effluents In the method for the humid treatment of effluents containing a compound selected from the group consisting of H2 SO4, free SO2, SO3-, or SO4= and having a pH lower than 5, the ... | 08/08/2000 |
| 6042794 | Process for producing anhydrous MgCl2 A process for producing anhydrous magnesium chloride comprising steps of selective calcination of Mg-containing minerals, selective leaching of magnesium, separation of insoluble impurities, precipitation of magnesium chloride hexammoniate and thermal dec... | 03/28/2000 |
| 5980842 | Separation of calcium from metal compounds A method of separating calcium from mixtures of metal oxides, sulfides, nitrates and carbonates. Particulate calcium containing mixtures are leached with nitric acid to form calcium nitrate and metal nitrates, which are heated to dryness and to form metal... | 11/09/1999 |
| 5362460 | Magnesium separation from dolomitic phosphate by sulfuric acid leaching Process for dissolving unwanted magnesium from phosphate ores by leaching with dilute sulfuric acid at automatically controlled pH. Minerals so treated are more easily converted by the conventional "wet" process into phosphoric acid, and yield better qual... | 11/08/1994 |
| 5122350 | Method for preparing calcium magnesium acetate and a residual mineral product by selectively calcining dolomite Fermentors, reactors and processes for preparing magnesium enriched calcium magnesium acetate (CMA) (Mg:Ca mole ratios of 1:1 to 20:1) by reacting a dolomitic lime product with a Mg:Ca mole ratio less than one with dilute acetic acid, such as in fermentat... | 06/16/1992 |
| 4978516 | Process for treating talc A process for improving a purity and/or whiteness degree of a talc powder is disclosed. A talc powder with a particle size of about 0.8 mm or less containing impurities such as asbestos, etc. is treated with a phosphoric acid agent under heating at from 7... | 12/18/1990 |
| 4871519 | Method of making magnesium oxide and hydrates thereof A process for producing magnesium oxide and/or hydrates thereof from predominantly magnesium or magnesium-calcium raw materials, and optionally producing calcium carbonate, whereby the raw material is roasted if necessary to form a mixture of magnesium ox... | 10/03/1989 |
