文摘

Frother type and concentration adjust gangue particle motion relative to water. Frother effect on ENT is a result of water motion at the pulp/froth interface. Frother affects water velocity and thus the drag at interface in determining ENT. The classification of entrained particles mainly occurs at the pulp/froth interface.
