The project is called Green Zinc Odda, and its energy consumption is based on fossil-free energy. Metso Outotec scope of delivery includes roasting and off-gas cleaning solutions and a sulphuric acid plant. Metso Outotec will also supply hydrometallurgical equipment and technology for calcine leaching, solid liquid separation, solution purification, as well as process and plant engineering and site services. Metso Outotec deliveries will take place in 2022-2024.

“We are very happy for being trusted with this order. The Green Zinc Odda project paves way for more sustainable zinc production and is yet another important milestone in the many years of collaboration between Boliden and Metso Outotec,” says Jari Ålgars, President, Metals business area at Metso Outotec.

Metso Outotec’s industry-leading zinc processing technologies consist of several proprietary Planet Positive solutions. These sustainable and cost-efficient technologies and services enable efficient zinc and by-product recovery from a wide range of primary zinc raw material.
