definition of recovery in froth flotation process

Kinetics of flotation. Order of process, rate constant distribution . The recovery of particles in the froth product (R) after flotation time (t) is defined as: 0 00 () ( ) =1 C C t Ct Rt CC (4) where C 0 is the concentration of floating particles remaining in the flotation chamber with the initial condition (t = 0). Generally, it isC 0 is t.

FLOTATION - thermopedia

Flotation is a process in Liquid-Solid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles, usually with objective of removing the solids from the liquid. The particles most effectively removed are in the size range from 10 to 200 μm. The particle-bubble aggregates that are formed have a density less than the suspension itself ...
