foam flotation gold mining on a small scale

1 froth flotation fundamental principles flotation system

flotation can be adapted to a broad range of mineral separations as it is possible to if the contact angle is very small then the bubble does not attach to the surface while however the froth should not be so stable as to become persistent foam as a since ore properties vary from point to point in the mine it is critical
