Methods the atomic absorption spectrophotometry (AAS) was used to determine the content of Pb, Cr, as, Hg and Cu in decoction and artificial gastric juice of Fluorite.
方法采用原子吸收分光光度法对紫石英在水煎液和人工胃液中铅、镉、砷、汞、铜的含量分别进行测定。
The ore is high in both fluorite has high content of both fluorite and barite, of that the floatability are similar and hardly to be separated.
某萤石矿石中萤石和重晶石含量高，但矿物可浮性相近，分离难度较大。
By adding sodium sulphide to depress quartz in the cleaning, high grade fluorite concentrate can be gained, whose content of silicon is under 1.0%, grade is over 97% and recovery is higher than 87%.
同时采用精选补加硫化钠抑制石英，得到了含硅量低于1.0%，品位高于97%，总回收率高于87%的高品级萤石。
In addition, the flowsheet structure and the content of heavy metal ions in the slurry have effects on the grade of fluorite concentrates as well.
另外流程结构及矿浆中重金属离子含量对萤石精矿品位也影响较大。
