礦物的磁力分離,是按照礦物所具有的不同磁性,用一定的工具(詳見後述)把它們分離開。这种工作好像很簡單,但是,礦物磁力分離的結果,却在地質研究工作中,起着一定的重要作用;例如:在砂礦研究和重砂分析工作中,礦物的磁力分离已经成為不可缺少的一個步驟。經过磁力分離后,不仅能便於礦物种類的鑑定,而且对於砂礦的來源問题,亦提供了比较可靠的資料。如我國某锡礦区的砂礦中,磁 Magnetic separation of minerals, minerals are in accordance with the different magnetic, with certain tools (see later) to separate them. This work seems to be very simple. However, the result of magnetic separation of minerals plays an important role in geological research. For example, in the study of sand and heavy sand, the magnetic separation of minerals has become indispensable A step. After magnetic separation, not only can facilitate the identification of mineral species, but also for the source of the placer, also provides more reliable information. Such as a tin mine in China’s sand, magnetic
