Project Brief

Increase lost coal production due to poor flotation performance, not enough floatation and thickener capacity - 1.5% lost yield.

Requirements

• Project aligned with structural integrity issues of tailings and concentrate sump- holed and risk failure
• Scope of project was to remove existing sumps and upgrade with larger sumps as well as additional pumps for redundancy
• Scope also allowed for filtration and Teetered Bed Circuit modifications to ensure lowest ash product in floatation/filtration circuit
• Significant works carried out during plant operation which added to the complexity of the project execution - balance of work complete within a 2 week shutdown period
• Project brief also included all project management, tender preparation and assessment, contractor selection processes and execution
• Budget - A$6 million 

Deliverables

• New pumps and sumps, filtration circuit modifications - froth volume unconstrained

Business Outcomes

• 1.5% increase in yield
• Froth volume unconstrained increasing fine coal yield
• Successful project completion, on budget and on time
• Zero incidents
