A tailings recovery process comprises: feeding ore pulp into a concentration barrel of a concentrating machine; driving the concentration barrel to rotate around its own central axis while the ore pulp flows, so as to enable the ore pulp to be continuously stirred and turn over in inner cavity of the concentration barrel; applying a magnetic field to the ore pulp by means of a magnetic field ...
liminary concentrate, or to reject tailings that contain no valu-able material at an early stage. The equipment used in this ap-plication are referred to as roughers. Roughers may produce a large amount of concentrate, permit the recovery of a very high percentage of feed gold, produce clean tailings, or produce a combination of the above.
Sep 15, 2020· Angular velocity (Ω) vs. bob stress for a 1.9 wt% clay suspension measured on different Couette devices. Also shown is the angular velocity corrected for wall slip (Ω f) vs. bob stress (adapted from Yoshimura and Prud'homme [10]). Commonly, concentrated tailings show a non-Newtonian behaviour where they have an elastic limit.
