How To Extract Gold From Sand? Mining-pedia

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.
