A hydrocyclone can handle very high slurry throughput rates, and often an entire battery of hydrocyclones can be found at a mineral processing facility. The advantage of fast processing by a hydrocyclone is somewhat offset by the associated high impingement wear rate of the hydrocyclone internal surface lining by the fast-moving abrasive slurries.
Recycle rate can be obtained by direct measurement of both flow rate and density of the combined cyclone underflow, so long as this is not roping. d.
