一、综述跳汰选矿法应用广泛,历史悠久。但其理论研究方面相当落后。已有的研究和建立的假说都未能正确反映跳汰机中的真实复杂情况,造成这种现象的重要原因之一是实验技术和测试方法的落后。众所周知,影响物料在跳汰机中分层的因素很多;但最主要的除矿物比重外就是支配矿粒运动和促使床层松散的水流运动特

First, review Jig dressing method is widely used, has a long history. However, its theoretical research is quite backward. The existing research and the established hypotheses fail to correctly reflect the real complicated situation in the jig. One of the important reasons for this phenomenon is the lagging of experimental techniques and testing methods. It is well known that there are many factors that affect the delamination of materials in the jig. However, the most important mineral additions dominate the movement of mineral particles and promote the movement of loose bed flow
