FLOTATION METHOD AND DEVICE FOR SPLITTING TAILINGS, AND USE THEREOF

摘要

A flotation method for splitting tailings comprises: disposing a spiral channel (2) on an inner wall surface of a flotation chamber (6), so that the tailings are split to the spiral channel (2) and enriches the spiral channel (2) after entering the flotation chamber (6); after entering the flotation chamber (6), an effluent ore pulp flowing upward in a spiral manner by means of an inertia force, mineralized bubbles floating upward to a central flotation area, and meanwhile the tailings sinking toward an area near the inner wall of the floatation chamber (6); by means of the gravity of the tailings and a centrifugal force applied on the tailings, the tailings flowing downward along the spiral channel (2), gradually enriching the spiral channel (2), and making a diffusion space with a great concentration difference for newly generated tailings in the floatation chamber (6), so that the concentration of tailings in the floatation chamber (6) is quickly reduced, and bubbles and mineralized bubbles that enter the spiral channel along with the tailings are extruded and escape under the gravity of a tailings layer, thereby eliminating bubbles and mineralized bubbles carried by the tailings, and implementing a floatation process for splitting tailings in the spiral channel (2). Also disclosed are a device for implementing the method, and a use of the method and device. The method and device, and the application thereof improve the quality of the mineralized bubbles.
