Gravity Concentration in Mineral Processing
Nowadays gravity methods of separation are used to treat a variety of materials , ranging from minerals with high specific gravity like galena , a heavy metal sulphide to low density materials like coal . Particle sizes being processed vary from 50mm in most cases to microns in some cases. The relative simplicity of gravity
