摘要
研究在恒温20℃、一定的搅拌速率及加水量不变的条件下,溶解不同量的光卤石,开展光卤石分解制氯化钾结晶机理研究实验。研究结果表明:光卤石溶解制氯化钾结晶机理为:氯化钾是先溶解后结晶的过程,即KC1先溶解到溶液中,当溶液中KC1达到一定过饱和度后再从溶液中结晶析出。
Dissolution crystallization mechanism of carnaUite was studied. Experiments were carried out under the conditions of stable temperature 20℃, certain stirring rate and unchanged amounts of water, with the different amounts of dissolved carnaUite. The results showed that carnallite dissolved in the water was a process that potassium chloride dissolved firstly and then KC1 crystallization appeared when certain supersaturation of KC1 was got.
