摘　　要：钾盐镁矾是一种重要的矿物资源,其产物被广泛使用在众多领域。本文详细研究了克鲁里矿床钾盐镁矾的分解过程及其温度影响规律。进行了一系列实验,实验结果显示,矿石压碎粒度的降低对分解效率无显著影响,而调整分解卤水成分和提高固/液比则能有效改善分解产物的粒度分布。钾盐镁矾分解的温度影响效应研究结果表明,矿石温度和卤水温度对钾盐镁矾分解产物含量具有显著影响。随着卤水温度增加,钾镁矾和钾盐含量先增加后减小,岩盐和钾盐镁矾的含量先减小后增加。此外,当矿石温度增加时,钾镁矾的含量降低,岩盐、钾盐镁矾和钾盐的含量增加。因此,在进行钾盐镁矾分解时,可以适当提高卤水温度可促进钾镁矾和钾盐的分解,但过高温度可能引发副反应,导致分解产率下降。本研究为克鲁里矿床钾盐镁矾资源的开发利用提供了重要的理论依据和技术支持。Kainite is an important mineral resource,and its products are widely used in many fields.In this paper,the decomposition process of kainite in Krulli deposit and its temperature influence law are studied in detail.A series of experiments have been carried out.The results show that the reduction of ore crushed particle size has no significant effect on the decomposition efficiency,but the adjustment of brine composition and the increase of solid/liquid ratio can effectively optimize the particle size distribution of decomposition products.The study results of the temperature influence effect of kainite decomposition show that the ore temperature and brine temperature have significant influence on the content of decomposition products of kainite.With the increase of brine temperature,the contents of kainite and potash increase first and then decrease,and the contents of rock salt and kainite decrease first and then increase.In addition,when the ore temperature increases,the content of kainite decreases,and the content of rock salt,kainite and potash increases.Therefore,the decomposition of kainite and potash can be promoted by appropriately increasing the brine temperature during the decomposition of kainite,but too high temperature may lead to adverse side effects,resulting in a decrease in the decomposition yield.This study provides important theoretical basis and technical support for the development and utilization of kainite resources in Krulli deposit.
