A typical project includes:

• Plant audit to ascertain the condition of existing plant instrumentation and control and the payback period of an instrumentation and control upgrade.
• Flotation Pulp level measurement instruments,
• Slurry Analysers for grade measurements of both elemental and mineralogy.
• Advanced process control for making use of all available plant measurements for upgrading the recovery performance.

Flotation Circuit

Benefits

• Increased Recovery
• Accurate Grade Control
• Optimise reagent usage

Flotation is a complex, multi-variable, interactive process that needs Advanced Process Control tools to effectively stabilise the operation and optimise grade and recovery within the design-related limitations of the plant. The LTM conductivity level measurement provides a very robust solution to the problem of flotation cell pulp level measurement. The Froth Image Analyser can measure froth velocity, height and froth volume recovery.  FloatStar was specifically developed for this purpose, and include tools like:

• FloatStar Level Stabiliser and pH Control
• FloatStar Flow & Grade-Recovery Optimiser
• FloatStar Reagent Control

Fault detection and controller performance monitoring is part of all the control suites.
