摘要
这是一篇矿物加工工程领域的论文。针对西北某重晶石矿分布不均匀、嵌布粒度粗细不均、重晶石与石英嵌布关系极为密切等特点,进行了详细的选矿工艺实验研究,研究结果表明:水玻璃作为抑制剂、氧化石蜡皂作为捕收剂可有效实现硫酸钡与脉石的分选,采用快速+强化浮选工艺,减轻了精选作业负荷、强化了硫酸钡的综合回收,小型闭路浮选实验获得重晶石精矿中硫酸钡品位89.16%、SiO_(2)品位0.85%,硫酸钡回收率92.01%的较好技术指标,重晶石精矿产品品质达到钻井用重晶石粉质量标准。
This is a paper in the field of mineral processing engineering.According to the characteristics of a certain barite ore in Northwest China,such as uneven distribution of barite ore,uneven dissemination particle size of barite,and extremely close dissemination relationship between barite and quartz,a detailed beneficiation process test was carried out.The research results show that:Sodium silicate as depressant,oxygen fossil sodium soap as a collector,which can effectively realize the barium sulfate and gangue separation,using fast segmentation strengthened flotation technology,reduce the selected operation load and strengthening the comprehensive recovery of barium sulfate,small closed-circuit flotation tests with the grade of barium sulfate in the barite ore concentrate 89.16%,the SiO_(2) grade is 0.85%,recovery rate of barium sulfate 92.01%better technical index,barite ore concentrate products meet brick wells with barite powder quality standards.
