现在岩矿鉴定最常用的方法是选取代表性的原矿样制成光片和薄片,在反光显微镜和矿物显微镜下进行研究。但是这种方法对少数个别类型的矿石则难有效,尤其是对嵌布极细的氧化矿和细粒包裹的氧化矿等更无能为力。碰到这种情况只能用物相分析、X 光晶体分析等方法来决定其矿物组成,但对其结构情况、颗粒大小及嵌布特性则无法知道。因而不能满足选矿研 Now the most commonly used method for the identification of rock and mine is to select representative raw ore-like sheets and sheets for investigation under a reflective microscope and a mineral microscope. However, this method is not effective for a few types of ore, especially for the extremely finely-packed oxide ore and fine-grained oxide ore. In this case, only the phase analysis, X-ray crystal analysis and other methods to determine the mineral composition, but its structure, particle size and embedded features can not know. Thus can not satisfy the dressing research
