Allmineral Aufbereitungstechnik GmbH & Co KG

Innovative separation and processing technology

allmineral - successful over more than 30 years, founded in Duisburg in March 1988.

Key products which ensured the company's rapid progress were its alljig® gravel jigging machines for separating contaminants from gravel and sand. In the early nineties the company introduced its all-new allflux® fluidized bed separator. This machine made it possible for the first time to classify large volumes of sand/water slurries and concurrently remove organic impurities in a single pass.

Alongside these successes in the gravel and sand industry, the company continued its activities in the traditional processing technology arena, especially with its jigs for coal and ores. The world's largest plants use alljig® jigging machines, such as a 2000 t/h coal-washery in the USA and a 4.000 t/h iron ore beneficiation-plant in South Africa. With over 800 machines sold to date, allmineral has definitively developed into the world's market leader in jigging technology.

Yet the company focuses not only on wet processing – it also offers expertise in dry processing technology. The allair® air jig for the beneficiation of coal and lignite in a dry environment without the use of water represents an absolute novelty with respect to specific capacities and performance. Since the industrial introduction of this innovative technology in 2002, allmineral has delivered over 60 machines to coal mines respectively power stations as well as DRI- plants in the USA, India, Columbia, the Ukraine and the largest plant of its kind; a 600 t/h coal processing plant in Spain.

Since early 2007 the product range has been supplemented by a wet high-intensity magnetic separator. The allgauss® magnetic separator is used to sort fine-grained, paramagnetic ores like hematite iron ores with capacities of up to 1400 tph per unit, the biggest WHIMS in the market. Another application of the allgauss® is the separation of iron contaminants from industrial sands.
