Acid decomposition of difficultly soluble potassium ores with the use of organic solvents

The dissolution of polyhalite ore in a hydrochloric acid solution at temperatures 50–100°C and salting out of potassium and magnesium sulfates from the obtained solutions with the use of selective organic solvents was studied. The effect exerted by temperature and solvent type on the extraction proc...

Zusammenfassung:	The dissolution of polyhalite ore in a hydrochloric acid solution at temperatures 50–100°C and salting out of potassium and magnesium sulfates from the obtained solutions with the use of selective organic solvents was studied. The effect exerted by temperature and solvent type on the extraction process was determined. A principal scheme of the ore processing was suggested.
