Metso receives equipment order for a zinc smelter expansion in South Asia

Metso has been awarded an order to supply key cellhouse process equipment for a zinc smelter expansion project in South Asia.

The customer is one of the leading zinc producers globally. The value of the order, which is not disclosed, is booked in the Minerals segment’s 2Q26 orders received.

The zinc plant project is based on Metso’s calcine leaching, solution purification, and cellhouse process technology. The delivery includes the latest high-capacity zinc cathode stripping machines, an anode washing and flattening machine, as well as the largest entity of cooling towers supplied by Metso to date, designed to maintain optimal electrolyte temperature and support efficient electrolysis performance. Metso will also provide advisory site services during project implementation.

“This project marks an important continuation of our long-term partnership with the customer. Metso’s proven technology and advanced equipment provide a reliable foundation for helping the customer achieve higher efficiency and productivity in their zinc refining operations,” says Marko Lahtinen, Sales Director, Hydrometallurgy at Metso.

Metso has previously delivered similar kinds of cathode and anode machines to the customer’s plants, all of which are based on Metso’s process design.
