Gravity Concentration Process

Historically the earliest method used,particles can be classified based on their specific gravity. Air is the main fluid medium used for the process. Gravity concentration processes include:

1. Heavy media or dense media separation (these include, baths, drums, larcodems, dyana whirlpool separators, and dense medium cyclones)
2. Shaking tables, such as the Wilfley table
3. Spiral separators
4. Reflux Classifier
5. Batac jigs
6. Centrifugal bowl concentrators, such as the Knelson concentrator and Falcon Concentrator
7. Jig concentrators are continuous processing gravity concentration devices using a pulsating fluidized bed.(RMS-Ross Corp. Circular Jig Plants)
8. Multi gravity separators (Falcon Concentrator, Knelson, Mozley and the Kelsey Jig)
9. Inline pressure Jigs
10. Reichert Cones
