摘要: 进行了青海马海盐湖含泥钾矿组成和结构以及脱泥技术研究。研究结果表明:矿泥主要成分为硅铝酸盐,矿泥的颗粒大小主要集中在100~160 μm,矿泥大部分被包裹在盐类矿物晶体间,或单独以微薄片层结构分布。采用旋流-筛分组合工艺可将氯化钾品位在8%~12%的含泥矿富集为氯化钾品位为16%~20%、含泥量为10%~15%(质量分数)的优质矿;而氯化钾品位为4%的高含泥矿,可富集至氯化钾品位为8%、含泥量为10%~15%(质量分数)的钾矿,该矿与优质矿掺兑使用,可进入车间进行生产。本研究可为含泥钾矿的高效利用提供一定的技术支撑。

Abstract: Chemical compositions,structural characteristics,and desliming technology of the slime-containing potash ores in Mahai Salt Lake of Qinghai were studied.Results showed that main constituent of slime was aluminum silicates,the particle size of slime was mainly in 100~160 μm and most of slimes filled among the crystal particles of salt minerals or existed in micro-film structure.Grade of potassium chloride could be increased to 16%~20% and the content of slime was at 10%~15%(mass fraction) when the grade of potassium chloride was at 8%~12% by using hydroclone-sieving combined technology.Grade of potassium chloride could be increased to 8% and the content of slime was at 10%~15% when its grade was 4%,and then it can be mixed with high grade potash ores to produce potassium chloride in plant.This study can provide a powerful technical support for the utilization of slime-containing potash ores.

Key words: slime-containing potash ores, hydroclone-sieving, desliming
