With the most recent incorporation of allmineral Australia Pty Ltd allmineral directly contributes to the remarkable expansion of Western Australia’s iron ore mining industry. This direct investment provides for an even stronger market presence of allmineral in Western Australia concurrent with further improved customer services.
At the same time it demonstrates its high appreciation of existing and future Australian customers in supporting them in a highly competitive market. There is an increasing demand for allmineral’s modern processing technologies being capable of turning low grade ore from the Pilbara area into high-quality products. After the successful and strategically important installation of Rio Tinto’s pilot plant containing allmineral’s core processing equipment types alljig®, allflux® and gaustec® WHIMS, allmineral continues its success: in 2011, allmineral secured contracts for another 12 jigs type alljig® as well as 14 fluidized bed separators type allflux® for the Pilbara. In the course of 2012 17 alljig® and 25 allflux® will be in operation in Australia finally. Manufactured and pre-assembled in Western Europe (Fig. 1 and Fig. 2), the machines undergo tough factory tests prior to being shipped to Australia (Fig. 3). Currently allmineral’s workshops are crowded with machines – most of them ready to leave for the Pilbara – while allmineral’s experts are completing the final testing.
The throughput rates of the allflux® fluidized bed separator are 180 respectively 250 t of iron ore per hour. The material (particle size < 1 mm) is separated in two stages based on particle size and density. The flow and control equipment facilitates the generation of three highly selectively graded products from a single machine, including thickening and desliming. The air- and side-pulsed alljig®-F-2500 jigging machines utilize the density differences between the iron and the lighter minerals in the ore for efficient separation. Due to the fact the jigging machines can be flexibly adjusted, they are able to precisely separate ores from 1 mm up to 8 mm. The alljig®-F-2500 operates physically stable at a throughput rate of 120 t of iron ore per hour with minimal energy consumption. The entire capacity of the new allmineral processing equipment in the Pilbara region is thus approximately 4500 t/h, i.e. around 30 million t/a.
Overall, allmineral has installed 17 alljig® machines, 25 allflux® machines and 1 gaustec® high intensity magnetic separator in Australia so far.
