Knelson gravity concentrators are the leaders in free gold recovery in Africa! Blanket started production in 1904. Early workers mined the visible gold sections of the pay shoots, i.e. pick the "eyes" out of the mine. Following on the significant early production milestones were: in 1965 Falconbridge acquired the property and increased …

The first Knelson Concentrator was trialled in 1976, 40 years ago, and Knelsons have been at the forefront of the industry ever since. Through all those years, Knelson has been widely accepted as the gold standard of gravity recovery. Not long after the first Knelson was unveiled, other companies and would-be manufacturers picked up on the idea ...

This is because the falcon is operated at higher rotation speeds than the Knelson™, without fluidizing water. Because of large rotation velocities, the Falcon concentrator lowers both the size of the optimum and minimum recovery below 25μm. In particular, the batch Falcon is effective in the fine range (less than 37μm for gold).
