The processing capacity of the alluvial gold beneficiated by the shaking table is small, but the enrichment ratio of the concentrate produced by it is high. It is suitable for the beneficiation process, for example, it can be used for the beneficiation of coarse concentrates from jigs, sluice boxes, and spiral concentrators.
