Gravity Separation - ScienceDirect

2016-1-1  So gravity separation has a long history as a mineral concentration process. Not all mineral combinations are amenable to this type of concentration technique. To determine the suitability of gravity separation processes to a particular ore type, a concentration criterion is commonly used.

mineral processing - Concentration Britannica

mineral processing - mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation),
