2. Dry separation equipment Dry beneficiation techniques can be divide into two main categories: beneficiation on air table and separation by air jigs. Air tables work by using ever-rising stream of air. Work plate can also vibrate to increase the accuracy of separation. Obtaining of the products depends on construction of the table.

In the mineral processing industry, ore grinding is the particle size preparation before the separation of the crushed ore. Except those that process some placers, almost all mineral processing plants have grinding operations, in which materials are crushed by the impact and abrasive action of grinding medium (steel rod, steel ball, gravel, or ...
