摘　　要：选矿技术主要有重选、磁选以及浮选三个。而目前重选工艺在选矿技术中仍然处于不利地位,但是关于它的研究一直在进行当中。重力选矿中的矿物表面特性是研究的重点,因为不会有很多的人去观察粒子流动的真正原因。由于大多数重力选矿的情况下,矿粒大多是比较粗的颗粒,而矿物表面特性的影响也许会被忽视从而选用惯性因素来选定。但是,在目前看来,处理许多粒度较细矿物愈加重要。There are three main mineral processing technologies, such as re-election, magnetic separation and flotation. The re-election process is still at a disadvantage in the beneficiation technology, but research based on it has been ongoing. The surface properties of minerals in gravity beneficiation are also the focus of research, because they cause little change in the fluidity of the particles. Since most of the gravity dressings, the particles are mostly coarse particles, and the influence of mineral surface characteristics may be neglected and selected by inertia factors. However, it appears that it is increasingly important to handle many finer-grained minerals.
