It is a double salt widely used in medicine and in the water purification process. Potash alum is not a complex salt. The chemical formula of potash alum is K 2 SO 2 (SO 4) 2 O. Aim: To prepare potash alum from potassium sulfate and aluminium sulfate through crystallization. Theory: The formula for potash alum is K 2 SO 2 (SO 4 ...
Sulphate of Potash Product Description. Analysis: 005018S. Also known as SOP, or potassium sulphate, this product is produced with a variety of processes and source materials; however, most commonly, natural Kcontaining minerals ( kainite and ite) are mined and rinsed with water and salt solutions to remove byproducts, creating a concentrated form of K2SO4
Potash occurs in soft deposits generally associated with sodium chloride and varying amounts of clay slime, which because of its colloidal character, complicates the beneficiation process.. Potash ores generally contain 20 to 40 percent KCL with the balance being NaCl and a small amount of clay slime, the latter usually in the order of 1 to 1½%.
The next most common way to produce this type of potash fertilizer, accounting for about 25 to 30 percent of supply, is by reacting potassium chloride with various sulfate salts to form what is ...

Mar 13, 1984· Heretofore, a number of inventions have been developed in order to improve the process of manufacturing potassium sulfate from potassium chloride and concentrated sulfuric acid. These inventions can be classified definitely into two kinds, that is, a completely dry thermal decomposition process and a completely wet double decomposition process.
The Bureau of Mines investigated potash recovery from plant process and waste brines, using the energyconserving methods of solar evaporation and froth flotation. Factors such as temperature, wind velocity, and amount of precipitation affect brine evaporation rate, .
A novel integrated process for the recovery of sulphate of potash (SOP) from sulphate rich bittern is disclosed. The process requires only bittern and lime as raw materials. Kainite type mixed salt is obtained by fractional crystallization of the bittern.

GLASERITE PREPARATION BY SODIUM SULPHATE AND POTASSIUM CHLORIDE 445 (a) (b ) (c) (b (a ) ) the requirement of KCl for maximum yield of glaserite. The resultant solution and solid phases in each case were analyzed for compositions (Table 2). These solutions were subjected to solar evaporation for fractional crystallization of salts.
The present invention is directed to a novel integrated process for the recovery of sulphate of potash (SOP) from sulphate rich bittern. The process requires bittern and lime as raw materials. Kainite type mixed salt is obtained by fractional crystallization of the bittern, and is converted to ite which is subsequently reacted with muriate of potash (MOP) for its conversion to SOP.

Jun 25, 1996· 1. A process for producing potassium sulfate or potassium sulfate and sodium sulfate from potash and a sodium sulfate/water source, comprising the steps of: (a) subjecting a sodium sulfate source to conversion with potash in an aqueous medium to yield glaserite precipitate and .
The process has several advantages: (a) simplicity, (b) high recovery efficiency and (c) production of NaCl and mixed salts as byproducts. 4. Conclusions From the results presented in this work it is quite evident that the process developed offers enough incentive to utilize it for the recovery of leonite and magnesiumchloride ...
The sulphate of potash or potassium sulphate is produced by several processes as follows: 1. Decantation Process or Langbeinite Process. Langbeinite is treated with concentrated solution of potassium chloride to yield precipitates of potassium sulphate. K2SO4. 2Mg. 2Mg SO4 + 4K Cl = 3K2SO4 = 2MgCl2
The present invention relates to a process for the recovery of sulphate of potash (SOP) from bittern. Kainite is obtained by fractional crystallization of the bittern. Kainite is converted into ite with simultaneous removal of NaCl and the filtrate (SEL) is used for production of KCl. ite is reacted with aqueous KCl to yield SOP and the filtrate (KEL) is recycled in the kainite to ...
May 09, 2006· The present invention provides an integrated process for the recovery of sulphate of potash (SOP) from sulphaterich bittern. The process requires only bittern and lime as raw materials and affords, besides SOP, low boron containing Mg(OH) 2, gypsum and salt, as coproducts, all of which are obtained in pure form. BACKGROUND OF THE INVENTION
