Metso Outotec says it has been awarded a contract for the delivery of key technology to the Boliden Odda zinc smelter expansion in western Norway.

Approximately 90% of the €150 million ($170 million) contract has been booked in the company’s Metals Q4/2021 orders received and the rest in Minerals Q4/2021 orders received.

With the expansion, Boliden Odda is planning to increase its annual production capacity of zinc metal from 200,000 t to 350,000 t. Several by-products will also be produced.

The project is called “Green Zinc Odda”, and its energy consumption is based on fossil-free energy.

Metso Outotec’s scope of delivery includes roasting and off-gas cleaning solutions and a sulphuric acid plant, with the OEM also supplying hydrometallurgical equipment and technology for calcine leaching, solid liquid separation, solution purification, as well as process and plant engineering and site services. The deliveries are set to take place in 2022-2024.

Jari Ålgars, President, Metals business area at Metso Outotec, said: “The Green Zinc Odda project paves the way for more sustainable zinc production and is yet another important milestone in the many years of collaboration between Boliden and Metso Outotec.”
