Continuous Variable Discharge Concentrator (CVD)
- Water is introduced through a series of fluidization holes located in the concentrate ring(s).
- Feed slurry is introduced through the feed tube.
- When the slurry reaches the bottom of the cone it is forced outward and driven up the cone wall toward the concentrate ring(s).
- The slurry fills the concentrate ring(s) to create a fluidized concentrate bed.
- Pinch valves are actuated allowing concentrates to be drawn from the concentrate ring(s) at a controlled rate.
- Concentrates report to a dedicated launder while tailings flow out the top of the cone into the tailings launder

"At Meridian Gold's El Penon mine in Chile, Knelson concentrator performance is severely hampered by steel fibers! The fibers, 1.25" long by about 1/32", are reinforcement for the shotcrete used underground and by the time they get into mill feed represent 180 gpt compared to a gold head of about 10 gpt!! Not surprising that the Knelson makes a good iron concentrate contaminated with gold!!"
