Metso Outotec has signed a major engineering and technology contract as well as license agreements for the delivery of a landmark copper smelter complex to be built in Gresik, East Java, in Indonesia.

The project owner is PT Freeport Indonesia, and PT Chiyoda International Indonesia is the EPC contractor. Four-fifths of the approximately EUR360-million contract has been booked in Metals’ Q3/2021 order intake and the rest in Minerals’ Q3/2021 order intake.

Metso Outotec’s scope of delivery is based on the licensed, well-proven Metso Outotec Flash Smelting, Flash Converting and Lurec technology. It includes the design and supply of key process equipment and process control systems for the main areas of the smelter complex, the copper electrolytic refinery, the gas cleaning and sulphuric acid plant, the slag concentrator, and the effluent treatment plant.

Metso Outotec has previously provided certain front-end engineering design (FEED) and other advance engineering services for this 1.7 mtpa copper concentrate smelter complex. This smelter complex is expected to be commissioned in 2024.

“Our joint efforts with Freeport Indonesia and Chiyoda will set a new standard for the copper smelter industry in fulfilling the strictest international environmental standards and efficiency requirements. We are very happy to work together to implement this game changing copper smelter,” says Pekka Vauramo, president and CEO at Metso Outotec.

“We have worked with Freeport Indonesia and Chiyoda for several years to ensure and select the best available process design and technologies for the Manyar Project,” says Jari Ålgars, president, Metals business area at Metso Outotec.

Metso Outotec has delivered 51 Copper Flash Smelters around the world. Metso Outotec Copper Flash Smelting is the most widely applied technology for copper smelting in the world and one of the company’s Planet Positive solutions.
