potash production

Селективне вилучення хлоридів з твердого напівпродукту перероблення розчинів хвостосховищ калійних виробництв прикарпаття

In this paper the possibility of obtaining almost non-chloride products with the help of the experimental studies of selective extraction of sodium and potassium chlorides from intermediate product of processing solutions tailings potash industries - sediment of potassium-magnesium salts with a high chloride content (over 25 %) using aqueous organic extractant (acetone, methanol, ethanol) was proved. It is shown that to achieve a high yield of product the extraction process should be carried out in 40% aqueous acetone.
