A century after zinc production began in Odda, Norway, European metals company Boliden has officially inaugurated the expanded Odda zinc smelter, marking a significant milestone for the facility. The expansion increases the plant’s annual zinc production capacity from 200,000 tonnes to 350,000 tonnes, solidifying its position as Europe’s second-largest and the world’s most productive zinc smelter. Notably, the facility can now produce 1,000 tonnes of cast zinc per full-time employee annually.
The project involved extensive infrastructure upgrades, including the installation of a new roasting furnace, a sulfuric acid plant, and a modernized cellhouse. Additionally, the leaching and cleaning plant and the foundry were expanded and updated to enhance production efficiency.
Boliden President and CEO Mikael Staffas described the expansion as a historic achievement, emphasizing its role in producing the world’s most climate-efficient zinc. “This zinc will primarily be used for rust protection in various European applications, contributing to a responsible climate transition. It’s also a flagship for Norwegian industry, ensuring pride for another 100 years,” he stated.
Zinc, the fourth most widely used metal globally, is critical for protecting steel structures from corrosion. It is heavily utilized in the construction, automotive, and energy sectors, particularly in wind turbines exposed to harsh environments. Additionally, zinc plays a vital role in agriculture, addressing zinc-deficient soils to boost global food production.
