摘要： A metallurgical processing system for economically recovering metal values, such as columbium, tantalum, thorium, and uranium from dilute source solids, such as digestion sludges, by a series of steps including:1) slurrying the source solids with dilute hydrofluoric acid to produce a solid phase and a liquid phase containing dissolved tantalum and columbium, then extracting tantalum and/or columbium from the liquid phase by means of a liquid ion-exchange process and then, additionally;2) roasting the solid phase with sulfuric acid to recover and recycle hydrofluoric acid, leaching the roasted solids with dilute sulfuric acid to produce a disposable solid phase and a liquid phase containing thorium and uranium, and extracting thorium and uranium from the liquid phase by means of a liquid-liquid amine extraction process.

摘要： A method of making a cesium salt is described and involves reacting a cesium sulfate containing solution with lime to form 1) a solution containing at least cesium hydroxide and 2) a residue comprising calcium sulfate. The method further involves removing the residue from the solution and converting the cesium hydroxide that is present in the solution to at least one type of cesium salt. The present invention further relates to uses of the cesium salt as well as methods of making cesium hydroxide using lime. Also, methods of making alkali metal salts and alkali metal hydroxides are also described.

摘要： Disclosed is a method for producing a predetermined cesium compound. The method comprises treating a cesium-containing material with a suitable reagent to dissolve at least a portion of the cesium contained in the material and form a slurry; adding a base comprising slaked lime or calcium carbonate and an acid containing the anion of the predetermined cesium compound to the slurry comprising the dissolved cesium; and separating the predetermined cesium compound. In one embodiment of the invention there is provided a method for producing a predetermined cesium compound from an ore comprising cesium aluminosilicate comprising: treating an ore comprising cesium aluminosilicate with an acid to form a slurry and dissolve at least a portion of the cesium contained in the ore; adding a base comprising slaked lime or calcium carbonate and a quantity of an acid containing the anion of the predetermined cesium compound to the slurry comprising dissolved or solubilized cesium; and separating the predetermined cesium compound. A drilling fluid or heavy medium separation fluid comprising the predetermined cesium compound of the process and having a specific gravity of between about 1.2 g/cm.sup.3 and about 2.5 g/cm.sup.3 and having less than 85% by weight of the predetermined cesium compound on a solution basis is also disclosed.

摘要： A method for recovering at least one metallic element from ore or other material is described and includes reacting ore or other material with a salt capable of recovering the metallic element from the ore or other material to form a reaction product that includes the metallic element. The method also includes recovering the metallic element from the reaction product. To remove the metallic element from the reaction product, the method can involve crushing the reaction product to form a crushed material and dissolving the crushed material in a solvent to remove the precipitates, thereby leaving a sulfate solution containing the metallic element.
