一、前言重力选矿是一种古老的物理选矿工艺,至今仍是某些具有一定比重差矿石的主要选矿方法。但重力选矿法随着入选矿石颗粒减小,沉降速度下降,单纯依靠重力已不足达到有效分选。随着选矿科学的研究进步,各种选矿方法正互相渗透,互相结合,在重力场上增加离心力场或磁力场,或将浮选工艺与重选相结合,研制复合力作用场的新型选矿设备,是微细粒物料重选的发展方向。
I. INTRODUCTION Gravity mineral processing is an ancient physical beneficiation process and is still the main method of beneficiation with certain proportion of poor ore. However, with the beneficiation of ore beneficiation method to reduce the particle size, sedimentation rate decreased, simply rely on gravity has been insufficient to achieve effective sorting. With the advancement of mineral science, various beneficiation methods are penetrating into one another, combining with each other, adding centrifugal or magnetic fields to the gravitational field, or combining the flotation process with reselection to develop a new type of beneficiation equipment , Is the development direction of micro-particle material re-election.
