摘要
我国钾盐矿储量少而其可利用性又小于光卤石矿。本文总结了国内外光卤石矿加工工艺的优缺点，提出热溶解－冷结晶是解决我国光卤石生产钾肥的途径。
The resetves of sylvite are limitted in China.hence carnallit becomes one of the most important potassium minerals.In this paper,strong and weak points of different carnallite pro-cessing are disc used.A circuit of“heat dissolve- cold crystallization”,which would be the most suitable for producing potash fertilizer from carnallite in China,has been proposed.
