Linde plc announced it has signed a long-term agreement to supply high-purity industrial gases to PT Freeport Indonesia. Linde will build, own and operate an air separation unit (ASU) to supply oxygen and nitrogen to PT Freeport Indonesia's new copper smelter and refinery in Manyar, Indonesia. The new copper smelter, the largest copper processing site in the world, will process concentrates from PT Freeport Indonesia's Grasberg mine.

The new on-site facility is expected to start up in mid-2024 and will be one of the largest ASUs in Indonesia.
