Gravity Concentrators

The separation of particles based on their characteristic specific gravity is one of the oldest and most commonly used separation techniques.

There is a wide range of equipment for separating materials of different density. Such techniques often characterized by their applied medium, gas (air/dry) or liquid (water/wet), are in wide use today in the mining and recycle industries.

Outotec provides an array of gravity concentration equipment that utilizes advanced principles of hindered settling, normal gravity and centrifugal force to achieve separations. From equipment for the precise separation of small quantity samples to commercial scale equipment handling an entire mine’s production, Outotec has the equipment and solution for any application.
