    Apr 23 2020 In gold sand gravity separation when roughing with a chute or jig the coarse concentrate is usually enriched by a shaker with a very high ore ratio its recovery rate can reach more than 98 and directly get the final concentrate and abandoned tailings. The above process is generally used in small-scale low-grade gold sand concentrators.
