ABSTRACT:
A mineral processing device for floating relatively large particles and middling particles is disclosed. The device provides a uniform upward flow of pulp in a flotation zone. Gas bubbles are introduced into the pulp with minimal agitation. Agitation in the flotation zone is also controlled by a plate with a multitude of holes of varying size. The upward flow velocity in the flotation zone is controlled by means of a variable speed impeller and an adjustable partition. Further, a flotation process utilizing uniform upward flow is provided.
