| Abstract: | Effect of temperature, concentration and dosage of solvent, reaction time on K＋ leaching rate of polyhalite was investigated by leaching experiment with Ca（OH）2 solution as solvent. Then process conditions were optimized. The results show that when 5% Ca（OH）2 is used as solvent, the ratio of liquid to solid is 4 ： 1,temperature is 40 ℃ and stirring time is 3h, K＋ leaching rate can reach 90.06%.So the process is feasible for preparing potassium sulfate from polyhalite. |
