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 (A$313 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 tonnes per annum (tpa) of copper cathodes and 1.1 million tpa of sulfuric acid.

The new copper smelting line is based on Metso’s licensed, well-proven 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. The delivery also comprises site services and spares.

“We are very pleased about this order. The Outotec Copper Flash Smelting method, which is part of the Metso Plus portfolio, is the world’s most widely applied technology for large-scale copper smelting plants,” Metso minerals president Piia Karhu said.

Metso is a leading technology supplier to the copper processing industry, offering comprehensive solutions that span the entire production chain, from concentrate processing to refined copper.

The Metso Plus solutions enable significant reductions in CO₂ emissions, and improve energy- and water-efficiency, at the same time ensuring high metal recovery even from challenging raw materials.

Metso’s portfolio for copper smelting includes, for example, the industry-leading Outotec Flash Smelting and Ausmelt processes, complemented by Lurec technology for optimised gas cleaning and sulfuric acid recovery.

In addition, Metso offers advanced e-Scrap smelting technologies for the recycling of electronic waste and a comprehensive scope of lifecycle services. Since the 1950s, Metso has delivered more than 50 copper smelters to major customers around the world.
