Metso has won a major order for the delivery of engineering and key process equipment for a new primary copper smelter investment in Asia. The contract value of approximately EUR 180 million is booked in the Minerals segment’s 2025 fourth-quarter intake with options to extend the scope.
The planned production capacity of the copper smelter complex is 300,000 tpa of copper cathodes and 1.1 million tpa of sulfuric acid.
The new copper smelting line is based on the licensed, well-proven Metso’s Outotec® Flash Smelting, PS Converting and Lurec® technologies. It includes the design and supply of key process equipment for the main areas of the smelter complex, and the gas cleaning and sulfuric acid plant, copper electrolytic refinery, and precious metals refinery.
