Abstract: An improved method for production of K 2 SO 4 from mixed potassium salts such as kainite or carnallite. A mixed potassium salt such as kainite is obtained by solution mining, and the brine thereby obtained is mixed with a sulfate-rich brine in order to increase the potassium/sulfate molar ratio to its optimum value of 2: 1. The kainite is thus converted to schoenite and/or leonite from which K 2 SO 4 is produced. By recycling end brines and ensuring that the potassium to sulfur ratio is at its optimum value, the method disclosed has higher efficiency and smaller losses than processes known in the art.

Abstract: The present invention provides an integrated process for the recovery of sulphate of potash (SOP) and ammonium sulphate fertilizers from kainite mixed salt dispensing with magnesium hydroxide production. The process comprises, among other steps, producing calcium chloride from calcium carbonate through addition of hydrochloric acid; the calcium chloride being used for desulphatation of schoenite end liquor (SEL) obtained as liquid stream during decomposition of kainite mixed salt with water to obtain solid schoenite; using the resultant gypsum and carbon dioxide together with ammonia for the production of ammonium sulphate liquor and solid calcium carbonate, the latter being recycled in the process; producing camallite from desulphated SEL; decomposing the camallite to recover camallite decomposed product (CDP) which is further refined under ambient conditions to obtain pure potassium chloride (KC1) utilised in the preparation of SOP from the schoenite. Except for ammonium sulphate recovery in solid state, where required, all operations are carried out at ambient temperature.

At least a portion of the water soluble composition is dissolved in an aqueous medium to form an aqueous solution comprising K + , Mg 2+ , and SO 4 2- ions and a calcium containing solid. The calcium containing solid is separated from the aqueous solution to form a filtrate comprising K + , Mg 2+ , and SO 4 2 ions. A potassium containing salt is dissolved in the filtrate to increase the concentration of K + and SO 4 2- ions to form a concentrated liquor, and K 2 SO 4 is crystallized from the concentrated liquor. A system for processing polyhalite ore includes a countercurrent leaching apparatus, a first mix tank, an evaporator, and at least one crystallizer.

Abstract: Disclosed herein is an electrode material obtained using a polyol process and a synthesis method thereof. The synthesis method includes the steps of preparing a mixed solution by mixing a transition metal compound, a polyacid anionic compound and a lithium compound with a polyol solvent; and obtaining a resultant product by reacting the mixed solution in a heating apparatus. In conventional methods of synthesizing an electrode material, such as the sol- gel method and the solid reaction method, the electrode material is synthesized through a heat treatment process, which is a post-process. However, in the method of synthesizing an electrode material according to the present invention, there is an advantage in that the electrode material, which has crystallinity due to a structure such as an olivine structure or a nasicon structure, can be synthesized using a polyol process at a low temperature without performing a heat treatment process, which is a post-process. Moreover, there are advantages in that the nanoelectrode material synthesized by the method according to the present invention has a high crystallinity, uniform particles, and a structure having a diameter ranging from several nanometers to several micrometers. Further, according to the present invention, the electrode material has a high electrochemical stability such that the discharge capacity of the electrode material is not greatly decreased even though the initial discharge capacity thereof is high and it is charged and discharged many times.
