Efficient tailings dewatering solutions for sustainable mining 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 for treatment of coal, copper, gold, iron ore, lithium, sand or other tailings, we have the ideal thickening and dewatering solution for you!

All issues attached to tailings treatment – 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. 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. Combined with process simulation technology, machine and process control and proven local service, we are proud to be able to offer the full package from simulation to installation and process optimization.

A broad portfolio

covering the full solid/liquid separation process from sedimentation and dewatering to drying gives us the ability to configure a processing line for tailings that is tailored to meet your specific needs

In-depth understanding of process requirements

with an offer covering laboratory tests, sizing, engineering and process optimization we can tailor the right solution to help you achieve your goals at the optimal OPEX or CAPEX

Local support - worldwide

Strategically positioned warehouses with OEM replacement parts, engineered wear parts (consumables), and field service – with remote support for emergencies

Where we fit into your tailings process 

ANDRITZ 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 invested considerably in expanding our competence with the acquisition and integration of well-known names as Bird, KHD Humboldt Wedag, Rittershaus & Blecher, Netzsch Filtration, Escher Wyss dryers, Krauss-Maffei centrifuges, dryers, and filters, and Delkor Capital Equipment (Pty) Ltd. 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.
