NaCl不饱和的海水体系卤水-矿物平衡研究

STUDY ON BRINE-MINERAL EQUILIBRATION IN THE NaCl-UNSATURATED SEA WATER SYSTEM

本文用实验的方法研究了K,Na,Mg,Cl,SO_4-H_2O体系在NaCl不饱和条件下的卤水-矿物平衡关系,并与该体系对NaCl饱和的相图作了对比。研究成果有利于更深入地探讨盐类矿床的形成和演化,对钾盐生产工艺的制订亦有重要指导作用。本文对四川盆地富钾卤水的成因作了合理的解释。

Laboratory study has been conducted on brine-mineral equilibration in the K, Na, Mg, Cl, SO4-H2O system under the NaCl-unsaturated condition. Its comparison with the phase-diagram of the NaCl-saturated (100℃) system has also been done. The result of this study is beneficial for further exploring the formation and evolution of salt deposits; it also has guiding importance to working out the potash-salt production process. The study gives a reasonable explanation to the origin of brine with a high concentration of potash in the Sichuan Basin.
