OPF2 Vertical WHIMS Plant

Fortescue is implementing a process plant upgrade at its Christmas Creek mine, utilising Vertical Wet High Intensity Magnetic Separation (Vertical WHIMS) technology to increase recovery and upgrade performance for fine material currently processed in the Desands circuit.

Primero was awarded Fortescue’s OPF2 Vertical WHIMS Project at Christmas Creek, initially engaged by way of early contractor involvement.

The VWHIMS plant will improve product grade and mass recovery of product from the Desands unit operation at Fortescue’s existing processing facilities at Christmas Creek, using Vertical Wet High Intensity Magnet technology.

Scope of Work

The VWHIMS plant will improve product grade and mass recovery of product from the Desands unit operation at Fortescue’s existing processing facilities at Christmas Creek, using Vertical Wet High Intensity Magnet technology. The flowsheet is based on a simple and robust configuration, where wet screen undersize at a nominal -1 mm is treated in open circuit through a Low Intensity Magnetic (LIMS) stage, followed by a Vertical Wet High Intensity Magnetic Separation (V-WHIMS) stage to produce a concentrate stream and a tailings stream, which can be integrated with the existing process and auxiliary equipment.

The VWHIMS project comprises to redirection of the wet screen undersize stream from the existing scrubbing circuit to feed the brownfield magnetic separation plant. Plant design includes without limitation to:
