In the gold processing plants, gold miners often use them in combination. For example, first use a jig to obtain rough gold concentrate, then use a shaking table to further concentrate it. In a gold processing plant, gravity separation equipment is not enough. You may need crushing and grinding equipment to dissociate more gold.
