These improvements allowed for higher furnace on-line availability, higher throughput, and an ability to smelt more complex concentrates. Due to this, the project was successfully delivered within the agreed timescale, with the planned shutdown schedule of 65 days followed by a rapid ramp-up back to production. The total feed of 260 t/h, which exceeded the design value, was achieved. All performance guarantee values were demonstrated within the first 3-day trial.
Moving forward with relationships and opportunities
We grow and build on partnerships, with Norilsk Nickel and Metso Outotec already having a strong and long-lasting partnership working together. Together, the whole mission was conducted in an outstanding manner by firstly setting accurate targets, followed by the necessary studies and tests, through to the implementation of proprietary industry-leading technologies. Together with the Nornickel specialists, we were able to achieve such positive results.
In 2020, Metso Outotec was awarded a new contract to modernize the second line at the Nadezhda Metallurgical Plant. The contract value is approximately EUR 90 millions, and it includes engineering and delivery of a nickel flash smelting furnace as well as a heat recovery boiler with related automation and advanced digital products. Metso Outotec is looking forward to the delivery of the equipment, set to take place during the first half of 2022. Replacing the existing smelting line with the latest process technology and furnace structures will significantly increase the line’s capacity and availability, reduce metal losses and ease maintenance. The new line will also allow for the easy connection and efficient operation with potential future sulfuric acid production and neutralization projects.
“Metso Outotec is a long-term partner of Norilsk Nickel, supplying state-of-the-art equipment and technologies. Our cooperation allows us to solve the most important production and technological issues, such as increasing the reliability and efficiency of production,” says Sergey Dubovitsky - Senior Vice President, Strategy, Strategic Projects, Logistics & Procurement at Norilsk Nickel.
Metso Outotec is a leading supplier of smelting technology, with about 40 operational smelting lines around the world. The Flash Smelting Process is the cleanest smelting method available, giving high recovery of metals with low investment and operating costs. In collaboration with Norilsk Nickel, we’re able to provide customers with the resources and expertise they need to achieve their goals and further optimize their production. That’s why we are the partner for positive change.
