Introduction: In gravity separation, the shaking tables (gravimetric tables, shaker tables) are the most widely used and efficient sorting equipment for fine ore separation. The shaking table beneficiation is not just applied as an independent beneficiation method. Still, it is often combined with equipment such as jig separators, centrifugal concentrators, spiral …

Therefore, the tungsten ore beneficiation process is becoming more and more important. Tungsten ore. Tungsten ore is a rare metal that is widely distributed and exists in almost all kinds of rocks. Due to its low content, it can only be enriched through relevant geological processes before forming ore deposits for mining.
