Many gold mines tailing worldwide are now recycled by the process of re-election-flotation or re-election-carbon slurry process. The methods used for gravity recycling include amalgamation, slsuice chute, jigg machine, and shaking tabe. Mercury amalgamation poses a great threat to the health of the factory environment and the workers; the gold recovery rate of the chute, jigging and shaking table is not high of very low production on cencentrates (generally not more than 0.5%), and the strength is uneven, fine-grained minerals are difficult to be recycled, jigs have slight lost in the process. In addition, since the coarse-fine grain gold is not well recovered in the gravity process, the subsequent flotation has a poor effect on their recovery, or in CIL plant the leaching time is not enough to completely dissolve it, resulting in a part of the gold loss in the tailings.. If the tailings are recovred by a TPB800 vertical centrifugal centrifuge concentrator,the medium-fine grain gold can be completely recovered. Such sucessfull cases China likes Hunchun Zijin Gold Mine, Shaanxi Shenba Gold Mine and Huanglong Gold Mine are examples of successful operations.
