Where we fit into your process

When it comes to thickening and filtration in the iron ore industry, getting the right end product at the right cost is no simple task. Whether it’s magnetite or hematite, goethite, limonite, siderite – or tailings treatment - all types of rock demand their own approach. Thanks to our comprehensive range of separation solutions, we’re able to supply the most suitable processing solutions.

Process line for iron ore from production to tailings treatment

"With just four hyperbaric disc filters from ANDRITZ we can handle more than 1,000 tons of dry solids per hour. No other supplier could match these volumes with such low installation and maintenance costs."

Tailings dewatering: creating more value from waste

With our expertise and cutting-edge technologies for iron ore tailings, we are committed to helping you maximize water recovery while minimizing environmental impact. In order to reduce freshwater consumption, mitigate environmental risks, and achieve sustainable operations, it is crucial to recover as much process water as possible before recirculation. Our refined flocculant dosing, thickening, and filtration solutions produce drier tailings, reliably and efficiently. This helps you optimize storage capacity, reduce transportation costs, minimize the need for freshwater intake, and enhance the overall operational efficiency of your facility at minimum operating costs.
