The concentrator operates based on the principle of centrifugal force. When the drum rotates at high speed, minerals within the drum are subjected to centrifugal force. Heavier minerals are pushed toward the outer wall of the drum, while lighter minerals remain closer to the center, enabling the separation of minerals based on their density. The concentrator comes in two types: batch-type and Continuous Variable Discharge (CVD) models. These two types are suitable for different scenarios depending on the concentrate yield. The batch-type is generally used when the concentrate yield is below 0.1%, while the CVD model is more suitable for yields above 0.1%. The batch-type concentrator is primarily used for the recovery of precious metals such as gold, silver, and platinum group metals. The CVD model is suited for the concentration of heavy minerals with a high specific gravity, including ferberite (tungsten), cassiterite (tin), columbite-tantalite, chromite, ilmenite, rutile, hematite, and sulfides containing gold and silver. It is also applied for industrial mineral de-ironing and coal desliming.
