theory of gravity separation process in mining

AN INTRODUCTION TO GRAVITY SEPARATION IN MINERAL

A major physical separation process is by use of the difference in specific gravity of the particles. Two basic principles are involved; particle settling and flowing film separation.

Gravity Separation Gravity Separator JXSC Mining

Gravity separation is an effective method for separating minerals of significantly different densities. It is an industrial method of separating two components from a suspension or any other homogeneous mixture where separating the components with gravity is sufficiently practical.

Gravity Separation an overview ScienceDirect Topics

In cases in which the processes of sedimentation and gravity separation are insufficient to cause the settlement of suspended solids, certain chemicals (such as alum, starch, iron materials, activated silica, and aluminum salts) are added to cause settlement of the solids. This process is then called coagulation.
