Increase your froth recovery and grade using Flotation Watch solution

1. Flotation Watch
for mineral processing industry
Numcore Ltd

2. Flotation Watch
See Beyond The Surface
• Flotation Watch is a froth flotation
control solution that increases
recovery and optimizes grade
without contamination problems
• The solution uses Numcore’s
innovative probe sensor, which is
easy to install into the flotation cell
• Flotation Watch can be controlled
with and existing automation system
Note: This product uses software developed by Spread Concepts LLC for use in the Spread toolkit. For more information about Spread see http://www.spread.org

3. Increase in recovery is done by
Controlling froth stiffness and thickness with adjustment of chemicals

4. Measurement of froth stiffness and thickness
Is done by an innovative probe sensor
• The probe sensor is easy to install into the flotation cell with standar size flanges
• Flotation Watch is a low-maintenance solution, because contamination does not
disturb the probe’s measuring operations
Stiffness of the froth [kg/m3]
Froth
Thickness of the froth bed [cm]
Pulp

5. Case example
A Finnish mineral processing plant
• A Finnish mineral processing
plant uses Flotation Watch in
order to increase recovery and
optimize grade
• Flotation Watch is used in a
rougher cell of the zinc
flotation process
• Flotation Watch has been
connected to the existing
automation system
