Thickening circuit

Outokumpu Technology has been awarded a further contract for the Boddington Gold Mine Expansion Project, with the company now supplying the complete thickening circuit at the future mine.

The design and supply contract comprises four thickeners, one of which is a 74m high rate thickener, and is scheduled for delivery in May 2007. The SUPAFLO high rate thickener was selected due to Boddington’s requirement for handling of the high throughput. The SUPAFLO design is renowned for redefining thickening and clarifying methods around the world and for delivering consistent, superior performance.

The 74m Boddington thickener will also feature Outokumpu Technology’s high capacity centre column drive, part of its high-torque SCD drive series. The SCD drives are engineered to handle high throughput and coarse, high torque materials.

The SCD drive will be complemented by a 75 kW hydraulic power pack, complete with standby pumps. The thickener will also feature Outokumpu Technology’s patented Autodil and Turbodil systems to dilute the incoming feed.

According to Outokumpu, this order, which also includes a 27m and two 19m diameter SUPAFLO thickeners, means Outokumpu Technology has been awarded the contracts for the complete thickening package at Boddington.

This new thickening contract follows an earlier order for the complete flotation circuit at Boddington, which is jointly owned by Newmont and AngloGold Ashanti. The flotation circuit comprises a total of 47 flotation units, including 18 x TankCell -200, amongst others. The order also includes the world’s large Flash Flotation circuit, with the company supplying four Flash Flotation SkimAir, 1800 units.

Once again Outokumpu has won this contract in the face of international competition because of its experience and technical know-how. Outokumpu Technology is recognised as a global leader in both flotation and thickening processes. Outokumpu also provides strong local expertise to assist with installation and commissioning, full technical support and spare parts and offer comprehensive training packages to enable clients to optimise the performance and efficiency throughout the life of the equipment.

Almost all components for Boddington will be sourced from Australian suppliers, ensuring high standards for this demanding duty.

Some recent Outokumpu Technology contracts in the minerals processing area have ranged from a comprehensive solution in grinding, flotation, thickening and control optimisation for Lihir, floats and thickeners for Black Swan through to grinding contracts including First Quantum Minerals’ (FQM) Frontier project in the Democratic Republic of Congo, AngloGold Ashanti’s Cuiaba project in Brazil, and BPR Bechtel’s UTB project in Canada.
