Jan 12, 2018 4. 0 Size-Separation Screening and Classification. The size distribution of the particles must be controlled for a number of reasons at various stages of a mineral processing plant To enable undersized material to bypass the crushing or grinding circuit.
The crushing and grinding steps enable the exploitation of differences in physical properties such as gravimetric, magnetizability, and surface ionization potential to aid in separation (Apian, 1988). The separation processes typically employed are (1) gravity separators, (2) electrical magnetic separators, and (3) flotation separators.
Introduction to Mineral Processing 5 3.0 Liberation and Comminution 3.1 Liberation In order to separate the minerals from gangue (the waste minerals), it is necessary to crush and grind the rock to unlock, or liberate, valuable minerals so that they are partially or fully exposed.
Nov 26, 2019 Crushing ratio. The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm.
