| A method comprises the step of spray-drying a slurry of potassium cobalt hexacyanoferrate (KCOHEX) particles to provide monodisperse, substantially spherical KCOHEX particles. In a further step the spherical KCOHEX particles are activated by heating until their color changes from dark green to purplish black. The particles can be used free flowing, in columns or beds, or entrapped in a porous, nonwoven, fibrous web or matrix, to selectively remove Cs ions from aqueous solutions. | ||||||

| Disclosed is a process for purifying a cesium compound which includes an ionic impurity comprising: calcium, sulfate, magnesium or mixtures thereof comprising: reacting impurities comprising calcium, sulfate, magnesium or mixtures thereof in a solution including the solubilized starting cesium compound with suitable precipitating agents to form an insoluble precipitate including the impurity or impurities. Preferred precipitating agents include barium ion to precipitate sulfate ionic impurities as barium sulfate; hydroxyl ion to precipitate magnesium ionic impurities as magnesium hydroxide and to precipitate calcium ionic impurities as calcium hydroxide; and carbon dioxide or carbonate ion to precipitate calcium ionic impurities as calcium carbonate. Also disclosed is a process for producing a predetermined cesium compound. The process comprises treating a cesium-including 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, if necessary to produce the desired cesium compound, an acid including 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 process 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 including 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 a purified cesium compound and having a specific gravity of between about 1.2 g/cm3 and about 2.5 g/cm3 and having less than 85 % by weight of the predetermined cesium compound on a solution basis is also disclosed. | ||||||

| 186 | Thermally-driven ion-exchange process for lithium recovery | EP96117114.7 | 1996-10-24 | EP0770427A3 | 1997-07-02 | Leavitt, Frederick Wells |
Ions (e.g. lithium) can be removed or recovered from brines containing those ions and optionally one or more other ions (e.g. other alkali metal ions) by the use of a temperature-swing, ion-exchange process employing an ion-exchange material. The process depends on a change in the selectivity coefficient of an ion exchange material for the ions desired to be recovered with a change in temperature, resulting in desirable ions being relatively selectively released at one temperature and undesirable ions being relatively selectively released at another temperature. The process of the invention can be used to effect the separation of any ion (or set of ions) from another ion or from a set of ions wherein the selectivity coefficient for one ion (or set of ions) has a substantial temperature dependence, compared to that for the other ion (or set of ions). |

| The invention relates to a process for producing a high-density concentrated caesium and rubidium salt solution. According to the invention, uncalcined pollucite and/or calcined epidolite are ground to a grain size ∫ 0.1 mm, hydrothermally dissolved with Ca(OH)2 at a temperature of 200 to 280 °C, a pressure of 20 to 40 bar and a suspension density of 4 to 15 % wt. in a period of one to three hours and a mol ratio of SiO2 to CaO ≥ 1:2. The insoluble solids are filtered off and washed, calcium and lithium are removed by introducing carbon dioxide and filtering the deposited carbonates from the dissolution filtrate, the remaining solution is concentrated and the salts of caesium and rubidium are formed by the addition of an acid or acid anhydride up to a pH of about 6, the filtrate separated off after dissolution being used several times in the hydrothermal dissolution process. | ||||||

| 194 | METHOD FOR RECOVERING AT LEAST ONE METALLIC ELEMENT LIKE CESIUM FROM ORE | PCT/US2004015990 | 2004-05-21 | WO2004106564A3 | 2005-05-19 | BAKKE BART F; MADDEN DAVID |
| 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. The method is particularly directed to the recovery of cesium from silicate- or aluminosilicate-based ore like pollucite via clinker formation by reacting the ore at elevated temperature in the presence of a metal sulfate salt. | ||||||
