Abstract
Embodiments provide a fluid recovery system and method for use with concentrator systems for concentrating particles suspended in a fluid and where this suspension is recovered from a fluid stream drawn from the concentrator system. A controller is configured to control valve actuation to direct concentrate being drawn from the concentrator chamber through a recovery tube to a recovery reservoir based on fluid volume movement. The system can use a density sensor to detect density transitions in fluid in the fluid recovery tube to identify leading and trailing edges of a portion of concentrated particles in fluid suspension passing through the recovery tube and actuate recovery valves based on objectives for maximising particle recovery with minimal dilution.
