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.
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.
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%.
