Outotec releases three new products for sustainable tailings and water management
Published by Claire Cuddihy,
Leading mining process technologies and services company, Outotec, has combined their expertise in the development of leading tailings and water treatment technologies to develop three new pre-engineered plant products to help face the challenges posed by increasingly complex ore compositions.
Outotec Thickened Tailings Plant
The Outotec Thickened Tailings Plant is designed for the management and storage of tailings from concentrators. Tailings thickening helps to reduce environmental risks and results in less seepage from the tailings storage facility (TSF). Utilising Outotec's advanced control systems and thickener optimisation technology, the Outotec Thickened Tailings Plant offers stable process performance and consistent underflow density to ensure safe and cost-efficient TSF operation. It also enables the efficient recovery of process water, saves energy by reducing the need for slurry and water pumping, and simplifies mine closure for many applications.
In addition to thickeners, the delivery scope for the Outotec Thickened Tailings Plant includes the feed system, overflow and underflow pumping and piping systems, gland water system, flocculant feed system, as well as instrumentation and control systems.
Outotec Dry Tailings Plant
Dry tailings disposal is a viable alternative for tailings management offering significant benefits in terms of environmental sustainability, process water recovery, and TSF footprint. The Outotec Dry Tailings
Plant solution is a fully integrated design that comprises thickening, filtration, and dry material handling for the dry stacking of tailings, including all necessary supporting equipment and systems. This solution is particularly suited to areas where water consumption is a sensitive issue, or where there are strict requirements in terms of the safe operation, management, and eventual closure and rehabilitation of the TSF. Dry stack facilities are also resistant to high levels of seismic activity.
Dry tailings storage is generally considered the safest and most environmentally sustainable technology for tailings management, and Outotec can provide a complete pre-engineered solution including plant and equipment delivery. Our service offering includes tailings management audits, studies, as well as maintenance and remote support services.
Outotec Process Water Recycling Plant
The Outotec Process Water Recycling Plant is a fully automated standalone unit that enables recycling of process water by treating the water in a cost-efficient manner. The plant is specifically designed for concentrator plants, which dewater tailings and recycle the water back to the process. It enables undisturbed process performance by treating recycled water and removing accumulated substances to achieve the desired level of quality for the various duty points of the concentration process.
As the plant is a modular solution, based on predesigned water treatment units, it is fully configurable for each individual process. The modular design also means that the whole process – from design to implementation – can be completed as quickly and smoothly as possible. Outotec also offers a full range of complementary services including process assessment, laboratory and pilot scale testing and analysis, technical studies, and remote monitoring and support.
