The second aim was to enrich of −0,5 mm particle size with the Knelson Concentrator and a fine coal containing 2210 kcal/kg LHV with 55.89% ash content was obtained with 67.81% combustion recovery.

Experimentation. Artificially mixed slurries of clay, pure magnetite and quartz (1 kg) were fed into the Knelson concentrator at a solid rate of 200 g/min to evaluate the effect of clays (bentonite or kaolin) on the separation of magnetite. The feed slurry contained 10% magnetite, different amount of clays (0, 5%, 10% or 15%) and quartz.

For that specific situation, it was apparent that the Falcon concentrator tended to produce somewhat coarser sized, and lower grade concentrates, than those generated by the Knelson unit: Overall however, gold capture per cycle of operation was almost identical. Falcon VS Knelson pretty much performed the same.

The Knelson™ concentrator consists of an inclined, constant-angle bowl wall and fluidized riffles along the entire height of the bowl – a design that has been largely unchanged since the initial development. The Falcon concentrator began as a near-vertical, smooth-walled bowl that was specifically designed for fine gold recovery.

For decades, Knelson™ concentrators have been synonymous with industry-leading gravity recovery of fine gold and precious metals. As a top product in its field, no other system on the market has proven to surpass the performance of Knelson Gravity Concentrators.
