CASE STUDY POTASH 1. Technological task is the quality control of the final product - potash (with 95-99% KCl concentration), obtained in the result of the halurgical process (halurgical method - the processing of potash ores by hot leaching with further crystallization of potash salt from

Potash was first processed in the 19th century by hot leaching and crystallization of potassium salts from saturated saline solution (Titkov, 2004) However, this process consumes high heat energy (95100oC) and causes high corrosion of the process equipment Thus flotation of potash

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.

hot leaching process. A process first used in 1860 for the extraction of potash from sylvinite ore based on the differing solubilities of sodium and potassium chloride. The ore, which is a mixture of sodium and potassium chloride, is crushed and mixed with saturated sodium chloride.
