Tailings treatment continues to be one of the fastest growing challenges in the mining sector. Ultimately, all the issues attached to it – environmental risks, space constraints, and water scarcity – need to be managed as cost-effectively as possible, as the result is a waste product rather than one that turns a profit. This is why we have developed a broad portfolio, including a wide range of individual technologies as well as line solutions, that can be tailored to help you achieve your goals at the optimal OPEX or CAPEX for your specific operations.
Higher dryness and maximized water recovery with lower energy consumption? Or high specific throughput with a minimum equipment footprint? Whether you are aiming to increase water recovery, ensure safe dry stacking, or aim for efficiency optimizations such as automated polymer dosage or an intelligent filter press, we have the ideal solution for you. From new equipment and systems to upgrades of existing processes, our process audits can help you identify the best opportunities for enhancing productivity, safety, and capacity for practically any tailings stream from coal to iron ore.

© ANDRITZANDRITZ specialists have gained an extensive knowledge of tailings treatment processing through multiple projects at various mining and mineral companies all over the world. For more than a century, we have supported the evolution of industries from potash to iron ore. We at ANDRITZ know how to tailor our complete range of state-of-the-art technologies to meet your needs. And by exploring innovative new ways to safely handle tailings or automate and monitor remote facilities, we ensure that you are ready for the future as well.
Our current portfolio covers the full solid/liquid separation process from sedimentation and dewatering to drying and ensures an excellent throughput of high-quality products – all with low operating costs and maximum reliability.
Our portfolio covers a variety of thickening and dewatering technologies, ranging from thickeners to decanter or pusher centrifuges, and from heavy-duty belt presses or hyperbaric disc filters to filter presses. This diversity means that we are able to configure a processing line for tailings that is tailored to meet your specific needs.
ANDRITZ thickeners are designed to achieve the highest production rates without compromising efficiency. For all counter-current decantation (CCD) plants, the new and improved ANDRITZ inter-stage mixing and dilution system for CCD circuits helps to reduce the footprint and consequently cut CAPEX while maintaining low operating costs. The innovative paste thickener design facilitates highly clarified liquid recovery as well as maximum underflow densities. Learn more about this technology
High G-forces are needed to dewater slurries with fine PSD. The ANDRITZ decanter centrifuge A10-4 operates with high-speed design capabilities for dewatering tailings and fine solids. Its large diameter-length ratio allows you to handle high volumes and increased recovery rates. Learn more about this technology
Despite its small footprint, the robust design contains an impressive array of features, including a reliable belt tension system and a flexible drive (hydraulic or electric). Compared with conventional belt presses, the cost of ownership is minimal, remote service is simple, and a greatly extended lifetime of high availability makes the machine reliable, simple, and cost-efficient to operate.

We offer a wide range of filter presses with sidebar and overhead technology suitable for standard, medium-duty, and heavy-duty performance levels. Maximum flexibility is provided by the choice between simple manual to fully automated ANDRITZ sidebar filter press designs. Learn more about this technology
We have combined our proven filter press automation solutions with Industrial Internet of Things (IIoT) technologies to create new mechanisms and features that promise higher product quality combined with lower operating costs. Learn more about this technology
The STARDISC product family of vacuum disc filters offers you a highly efficient filter operation to achieve these objectives and gives you a decisive competitive edge. It provides a maximum level of flexibility and is based on proven technologies that you can rely on – day after day. Learn more about this technology
The ANDRITZ hyperbaric disc filter is the right choice whenever you require continuous filtration with maximum solids throughput, minimum residual moisture, and clear filtrate in a single unit, as is the case for coal and iron ore tailings. Learn more about this technology
Real-time, automatic adjustment of polymer dosage with the use of artificial intelligence to reduce your costs by up to 40%. Metris addIQ RheoScan has been developed to use AI to control the adjustment of polymers to the current sludge conditions in real time 24/7.
