FLOTATION LAUNDER DESIGN, DOES IT MATTER?

FLOTATION LAUNDER DESIGN, DOES IT MATTER? There are two key factors at play when deciding the flo-tation equipment selection for your circuit viz. residence time and froth transport parameters. Both are highly dependent on the specific ore characteristics such as mineral grade, liberation, flotation kinetics and specific gravity.

A plurality of radially oriented launders are placed near the top of the tank and have one end connected to an outer launder adjacent the outer periphery of the tank.

Slope of Flotation Slurry Launders for Froth Flow

Launders should have high enough velocities to prevent particles from settling, or if they fall to the bottom, to keep them rolling and sliding. The depth of water should not be much over the diameter of the largest rolling particles. For concentrates and heavy gangues slopes should be increased 25—100%. SPRAY WATER IN LAUNDERS:—While it is claimed that the quantity of water flowing with

Cross-flow filtration Wikipedia

Cross-flow filtration gets its name because the majority of the feed flow travels tangentially across the surface of the filter, rather than into the filter. The principal advantage of this is that the filter cake (which can blind the filter) is substantially washed away during the filtration process, increasing the length of time that a filter unit can be operational.

Flotation level measurement techniques explained April

Of interest in a flotation cell is how deep the froth is above the slurry, as this determines the grade of the resulting concentrate. The typical range for a froth depth is 600 mm from the top of the flotation cell, the launder, down to the slurry interface. Here we are actually trying to measure the depth of a froth

A multiphase mixture flow is discharged from the mixing passage into the vessel, where it flows past one or more longitudinal stabilizing baffles. Gas bubbles loaded with hydrophobic particles disengage from the stream, rise toward the liquid surface and are diverted by bubble-diverting guides toward a froth discharge end of the vessel.
