Dry separation of fine particulate sand mixture based

2020-9-1  1. Introduction. Separation of particulate solid materials is one of the most important unit operations in industry. Wet separations such as froth flotation have been utilized for fine particulate mixtures over the decades; such conventional wet separation processes require a large amount of water and are not feasible in dry districts.

Gravity separation techniques are used to separate minerals of different relative densities. The dominant competing force in gravity separation is usually a fluid drag force. Pneumatic tabling and winnowing have been included as dry forms of gravity separation, although in these cases particle shape will contribute significantly to product quality.

Magnetic separator with electrostatic enhancement

One of the problems associated with dry magnetic separation is due to the fine particle size, e.g. below 20 um. The centrifugal force acting upon the fine particle is so low that even static charge and/or agglomeration force can prohibit the removal of fine particles from the process surface (belt or drum).
