allmineral has been awarded three independent contracts to supply its leading mineral processing products and equipment to the Rio Tinto low-grade Iron ore pilot plant.

The Pilot Plant, which will be located at the Brockman 4 Mine Site in Western Australia, 60km north west of Tom Price, will play a strategic part in the optimisation of beneficiation options for future Pilbara lower grade deposits.

Through MSP Engineering – the contractor that successfully secured the complete jig package with Onyx Projects – allmineral will be providing an alljig® with a design capacity of up to 80 tph feed material. The alljig separates high density iron ore from gangue material using the processes of stratification and separation. The jig is fitted with flexible design features that allow it to treat fines and lump material up to 32 mm as well as treating wide ranging particle size ratios of up to 1:8.

allmineral also secured an order for its unique three product allflux® classifier, the model AFX 100 classifier. This unit is designed to treat up to 2 mm iron ore particles in two classification stages that upgrade the valuable mineral by size and density, and also do thickening and desliming in one step.

The third allmineral product specifically developed for the beneficiation of hematite ores that will be supplied to this Pilot Plant is the model G 1000 gaustec® wet high intensity magnetic separator (WHIMS). The WHIMS separates iron ores, including paramagnetic and feebly magnetic minerals, up to a particle size of 3mm if required but typically around 1mm. High gradient magnetic fields are used, which can be independently adjusted for each rotor, allowing scavenger and cleaner process steps to occur in one single machine.

The equipment being supplied comprises of our proven technologies in hematite beneficiation and we consider ourselves fortunate to be associated with the next generation large capacity downstream operations planned for the Pilbara, said Dr Heribert Breuer. He went on to say: We are confident that the upgrading processes for low grade iron ore have the potential to significantly add value to Rio Tinto’s existing and planned operations.

Onyx Projects is the engineering company that will provide the complete Pilot Plant facility to Rio Tinto, with start-up scheduled for late Quarter 4, 2011.

allmineral belongs to the leading suppliers of processing plants and equipments for the mining industry worldwide. With its superb technologies the Duisburg based company is well known as a specialist for the processing and separation of coal, ore, slag, gravel and sand as well as various secondary raw materials. Around the globe more than 600 allmineral installations for the wet and dry separation are installed.
