Outotec’s pioneering technologies help reduce water, energy, and raw material consumption and cut emissions and waste levels – and enable the company’s customers to use less energy and resources, while generating less waste and achieving lower life-time operating costs.
Outotec has been an innovator in minerals and metals processing technologies for close to a century, and has become a leader in areas such as chemicals, fertilisers, energy, and industrial water treatment, thanks to its highly efficient and environmentally sound expertise across the entire processing chain: from ore to refined metals.
As Outotec’s solutions are typically expected to last for decades, they are designed to have as small an environmental footprint as possible. In addition to process and energy efficiency and overall sustainability, high standards of performance in areas such as reliability, availability, maintainability, and safety are also prioritised.
With water in short supply at many mining sites, water-related technology has become an increasingly important key focus area for Outotec in recent years, and the company has developed numerous solutions for reducing process water needs by increasing water recycling and cutting wastewater levels.
A global expert
The common denominator in all of Outotec’s technologies is their ability to save energy, natural resources, and capital, often all at the same time. Environmental priorities are integrated into Outotec’s processes from the start, rather than being bolted on as an afterthought.
|Outotec is using the innovative new 3D-imaging technology to optimise processes such as flotation.
Simply developing and supplying advanced technology is not enough to ensure the sustainability of a customer’s project, however, which is why Outotec aims to offer its customers a comprehensive range of expertise: from feasibility studies, conceptual engineering, and process and plant engineering to equipment design and supply, and turnkey plant deliveries.
Outotec also works with customers after plants have been commissioned to ensure that they continue to run smoothly, providing knowhow in areas such as plant audits, optimisation, upgrades, maintenance, and training. When a plant comes to the end of its useful life, Outotec can help with shutting it down and repurposing the site for future use.
Innovative online process control solutions based on 3D-imaging
Outotec strengthened its process control expertise in 2012 by acquiring Numcore, a Finnish start-up specialising in innovative online process control solutions based on 3D-imaging. This technology – known as EIT (Electrical Impedance Tomography) – uses conductivity measurement techniques to see inside process vessels and pipework.
EIT has already proved what it is capable of in the control and optimisation of froth flotation processes, as it enables slurry and froth levels, as well as froth stiffness, to be measured very accurately. This know-how will be very useful for Outotec, which has supplied over 10,000 flotation units and more than 1,600 thickeners to the minerals processing industry over the last 20 years. EIT technology is also ideal for new types of flotation cells and thickeners, as it has the potential to increase metal recovery by optimising the froth flotation process, as well as production efficiency and reliability. The technology also has extensive application potential in other areas as well.
