What does chemical engineers do in minerals processing

MINERAL PROCESSING includes A. LIBERATION separating minerals into individual grains. Primary liberation is carried out by crushing. This is done in a jaw crusher at the mine. The grains are further liberated at a plant which is often on the mine site. Secondary liberation takes place at the crushing plant.

chain in the air phase. In fact, the frother creates conditions for froth formation. As fallowed, the flotation froth is a three phase system. The frother concentrates at the interface of water and air bubbles, forming an envelope around the bubbles, which prevents them from colliding or touching. Frothers also lower the surface tension of the water.
