单矿物分选是矿床成因、综合评价和物质成分研究等工作中的重要环节。单矿物分选的纯度,直接影响化学分析、x-光分析、光谱分析、同位素年龄测定、红外光谱、矿物的物理性质测定等的测试数据的精度,必须予以重视。但目前的单矿物分选方法远不能满足实际工作的需要,特别是对微细矿物的分选,更感困难。由于矿物间普遍存在着磁化系数的差异,因此,磁选仍然是广泛应用的方法。其中,等磁力型磁选机(Franz型,我国的wcF型)分选200目以上样品的效果是比较理想的,但对200目以下样品的效果,急剧降低。在解决微细矿物的分选问题中,如能扩大等磁力型磁选机的应用范围与
Single mineral separation is the cause of the deposit, comprehensive evaluation and material composition of an important part of the work. The purity of single mineral separation, which has a direct impact on the accuracy of the test data of chemical analysis, x-ray analysis, spectral analysis, isotope age determination, infrared spectroscopy and determination of the physical properties of minerals, must be taken seriously. However, the current single mineral separation method can not meet the needs of practical work, especially for fine mineral sorting, more difficult. Magnetic separation is still a widely used method because of the common magnetization coefficient differences between minerals. Among them, the iso-magnetic separator (Franz type, our country wcF type) sorting more than 200 mesh samples of the effect is ideal, but the effect of the sample below 200 mesh, drastically reduced. In the resolution of fine mineral separation problems, such as the magnetic flux-based magnetic separator to expand the scope of application
