Sep 25 2018 The choice of the beneficiation treatment depends on the nature of the gangue present and its association with the ore structure Several methods techniques such as jigging washing magnetic separation gravity separation and flotation etc are being used to enhance the iron percentage in the Iron ore and to reduce its gangue content.
The dry separation methods for coal beneficiation have been regaining attention in the past decades A number of improved or newly designed devices have been developed—one of them is a negative pressure pneumatic separator (NPPS) The said method of separation is based on the differences in the physical properties between coal and gangue minerals such as the grain density size and shape.
With this method the de centralised pre concentration of coal in small remote mines allows the coal to be separated from the waste rock to immense economic advantage Transport costs are massively reduced or the coal is sold directly as a high quality product The use of drum screens is very common in coal beneficiation.
