Outotec to conduct feasibility study for the first alumina refinery to be built in Indonesia

Outotec has agreed with PT ANTAM (Persero) Tbk (ASX: ATM; IDX: ANTM; Antam), Indonesia's leading diversified mining and metals company, to carry out a feasibility study for the very first smelter-grade alumina refinery to be built in Indonesia.

Indonesia is the sixth-largest bauxite producing country in the world. Nevertheless, thus far the domestic bauxite is not refined to alumina - key raw material in aluminum production - in Indonesia. Instead, alumina is imported from Australia to the aluminum smelter located in North Sumatra. Antam is therefore intending to build the first smelter grade alumina refinery in Indonesia, in order to utilize its vast bauxite deposits and develop an integrated value chain for domestic aluminum production.

The feasibility study which will be conducted by Outotec will include comprehensive mineralogical investigations, laboratory-scale hydrometallurgical tests and basic engineering of the alumina refinery.

"We are extremely pleased that our expertise spanning the entire value chain -- from ore to refined metal -- will be utilized in developing Indonesia's aluminum industry. The feasibility study for the new alumina refinery will be based on Outotec® Alumina Refining technologies which are energy efficient and sustainable," says Outotec CEO Pertti Korhonen.
