Knelson vs. Falcon Gravity Concentrators

The Knelson and the Falcon have been used to concentrate less dense mineral than tungsten (galena). In both concentrators, the recovery is less than with the tungsten. Again, a better recovery is obtained with the Falcon Gravity Concentrator. Introduction. Among the separation processes, gravimetry is probably the cheapest one.

Spiral concentrators are robust gravity separation devices that allow for concentration of slurry streams. Optimal splitter position (which determines recovery and grade) is dependent on the interface positions of the concentrate, middlings and/or tailings in the trough.

Falcon SB Gravity Concentrator | Mineral Processing Equipment

Outside grinding circuits, Falcon SB Gravity Concentrators are also used for precious metal separation from aggregate or placer deposits. Falcon SB Gravity Concentrators are known as Semi-Batch Gravity Concentrators because they continually accept feed during the run cycle, but only produce mineral concentrate during periodic rinse cycles.

The spiral output responses considered for modelling are tailings and concentrate HM grade, HM recovery, and concentrate-tailings flow ratio (simply the mass flow rate of concentrate divided by the mass flow rate of tailings). A flow ratio model gives a method with which to determine the overall mass balance around a spiral.

The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio. Also, detailed characterization ...
