FMS Floatation Overview

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay in the liquid phase. Froth flotation can be adapted to a broad range of mineral separations, as it is possible to use chemical treatments to selectively alter mineral surfaces so that they have the necessary properties for the separation.

FMS introduces two Flotation Systems Arrangement:

  1. 1.Six Cells Flotation Arrangement which include:
             a.Two Conditioner Tank with 50m3 Capacity
             b.Six Flotation Smart Cell with 50m3 Capacity
             c.Feed Tank with 10m3 Capacity
             d.Discharge Tank
             e.Reagent Preparation and Dosing System

  2. 2.Four Cells Flotation Arrangement which include:
             a.one Conditioner Tank with 50m3 Capacity
             b.Six Flotation Smart Cell with 50m3 Capacity
             c.Feed Tank with 10m3 Capacity
             d.Discharge Tank
             e.Reagent Preparation and Dosing System
 

Flotation Smart Cell

The cell will be a vertical cylindrical tank with an internal froth collection launder that will discharge to flanged connections on one side. Each tank will have one clean-out port with blind flanges located on the side of the tank at the bottom.

A false bottom and draft tube assembly is bolted to the tank bottom. The draft tube helps to draw the slurry up from the bottom of the cell to the flotation region around the rotor where it comes into contact with the air.

The SmartCell Mechanism

The SmartCell flotation mechanism differs from other flotation cells as the rotor is located at the top of the tank. The Star Rotor has a mild steel core covered with natural rubber or urethane.

The disperser is a molded urethane piece that surrounds the rotor. The disperser provides resistance to the flow from the rotor and creates an intensive zone where contact between the mineral particles and the air bubbles takes place.

With the top mounted rotor, the energy from the flotation process is nearer to the surface of the cell. Each Wemco mechanism is fitted with a disperser hood to dissipate excess energy from the rotor region and calm the cell surface for recovery of the froth.

The hood angle is selected to give a relatively flat froth surface but not to totally remove the benefit of the slurry movement towards the launder.
