研究的样品含BaSO_4大约16％,并且80％-325目。以前的浮选重晶石的方法,未能得到满意的品位和重晶石的回收率,其原因是给矿品位低,此外还含有6％的方解石。混合添加新的长碳链磺化丁酰胺捕收剂与高浓度的硅酸钠并采用简单的粗选-精选流程,所得到的重晶石精矿可达到油钻泥浆(oil-drilling mud)的需要。磨细的矿石并可不需脱泥。得到的重晶石回收率超过80％,精矿产品的比重大于4.3。在研究工作的过程中,应用了红外线(IR)分光光度计对试样中的重晶石,方解石,石英和长石进行了半定量的分析,还用热天平分析了方解石的含量。这些仪器能迅速地进行矿物分析。实验证明:使用这些仪器对指导浮选研究有很大的帮助。
The samples studied contained about 16% BaSO 4, and 80% -325 mesh. Previous methods of flotation of barite failed to achieve satisfactory grade and recovery of barite due to the low ore grade and in addition 6% calcite. Mixing Add a new long chain sulfonamide butyronamide collector with a high concentration of sodium silicate and using a simple roughing - selection process, the resulting barite concentrate can reach oil-drilling mud (oil-drilling mud ) Needs. Finely ground ore without mud removal. Barite recovery rate of more than 80%, the proportion of concentrate products is greater than 4.3. In the course of the research work, IR spectrophotometer was applied to semi-quantitative analysis of barite, calcite, quartz and feldspar in the sample, and the content of calcite was also analyzed by thermobalance. These instruments allow rapid mineral analysis. Experiments show that the use of these instruments is of great help in guiding flotation studies.
