摘要: 利用西台吉乃尔盐湖钾肥生产中副产尾盐矿为原料,根据尾盐固相矿物组成,通过转化、浮选法研究生产硫酸钾镁肥的工艺流程,并对尾盐矿粒度、调浆液量、不同浮选流程阶段、尾盐固相放置时间等主要因素进行条件实验,获得最佳实验条件。尾盐固相回收硫酸钾镁肥钾收率在55%以上,整个生产系统总收率提高24.8%以上,为硫酸盐型盐湖提高系统钾及镁元素的总回收率、加大资源综合回收利用提供了一种新的方法。

Abstract: Potassium-magnesium sulfate fertilizer was prepared via transformation and flotation method with tail salt from potash production in West Taijinar salt lake as raw material.The major factors including tail salt particle size,amount of adjusting slurry,different flotation process stage,and storage time of tail salt were investigated,and the optimum experimental conditions were obtained.The recovery of potassium-magnesium sulfate fertilizer from tail salt was more than 55%,and the total potassium yield of the entire production system was increased by more than 24.8%.It was revealed by results that this new process for recovery potassium-magnesium sulfate fertilizer from tail salt would improve the total recovery of potassium and magnesium in potash production and provided a new approach for sulfate-type salt lake resource comprehensive recycling and utilizing.

Key words: tail salt, flotation, transform, potassium-magnesium sulfate fertilizer
