摘要： The present disclosure relates to an onshore lithium-recovering device for a lithium ion adsorption and desorption process including a supply unit for supplying lithium-containing water in which lithium is dissolved, a composite unit, a washing unit, a desorbing liquid unit, an extract liquid unit, a pressure adjusting unit, a discharge unit, and a control unit. Therefore, the lithium adsorption means is moved onshore so it is possible to significantly reduce the plant installation cost and the operating cost as compared to the lithium recovery process that operates the conventional offshore plant.

摘要： In alternative embodiments, the invention provides processes and methods for the recovery, removal or extracting of, and subsequent purification of uranium from a wet-process phosphoric acid using a continuous ion exchange processing approach, where the uranium is recovered from a phosphoric acid, or a phos-acid feedstock using either a dual or a single stage extraction methodology. In both cases an intermediate ammonium uranyl-tricarbonate solution is formed. In alternative embodiments, in the dual cycle approach, this solution is contacted in a second continuous ion exchange system with a strong anion exchange resin then subsequently recovered as an acidic uranyl solution that is further treated to produce an intermediate uranyl peroxide compound which is ultimately calcined to produce the final uranium oxide product. In alternative embodiments, in the single cycle case, the intermediate ammonium uranyl-tricarbonate solution is evaporated to decompose the ammonium carbonate and produce an intermediate uranium carbonate/oxide solid material. These solids are digested in an acid medium, and then processed in the same manner as the secondary regeneration solution from the dual cycle process to produce an intermediate uranyl peroxide that is calcined to produce a final uranium oxide product.

摘要： The present invention relates to a continuous ion exchange methodology for production of ammonium-potassium polyphosphate solutions using agricultural grade phosphoric acid, anhydrous ammonia, and agricultural grade potassium chloride (ag potash) as primary feedstocks. The method is particularly applicable to the production of these low salt index, specialty liquid fertilizer solutions and allows for the use of less expensive ag-potash and impure phosphoric acid as the potassium and phosphate sources in order to produce the ammonium-potassium polyphosphate compounds, which are chloride free as a result of the ion ex-change process.

摘要： An apparatus and method for regenerating spent ion exchange resin and recovering regenerant fluid is described. A regeneration system has a regeneration vat, a regeneration solution tank, a regenerant recovery tank, a chemical dispenser, a solids separator, a pH adjuster and a pump. The regeneration vat holds the spent resin and is connected to the regeneration solution tank to allow transfer of regenerant solution into the regeneration vat. Spent regenerant fluid travels to the regenerant recovery tank, where it is treated with chemicals provided from the chemical dispenser. The solids separator receives the treated regenerant liquid and separates precipitate flocs from the treated regenerant liquid. The concentration of chloride ions in the separated regenerant solution can be adjusted by the pH adjuster to form fresh regenerant solution. The pump pumps the fresh regenerant solution to the regenerant solution tank to regenerate additional spent cation exchange resin.
