Outotec has signed a contract for the Front-End Engineering Design (FEED) of a new copper smelter to be located at Benete Bay in Sumbawa, Indonesia. The contract partner is PT Amman Mineral Industri, a subsidiary of copper and gold producer PT Amman Mineral Nusa Tenggara. The approximately EUR10 million contract has been booked in Outotec’s 2018 fourth quarter order intake.

Outotec’s scope of engineering covers the design of the entire copper smelter. The engineering will be based on Outotec® Flash Smelting and Flash Converting technology, and include an electrolytic refinery, slag concentrator, precious metals refinery, wet gas cleaning and Lurec® sulphuric acid plant as well as effluent treatment plant and its associated infrastructure.

Outotec’s design work will take place in the following nine months and is a continuation of the feasibility study conducted in 2017. Once completed, the new smelter is planned to primarily process Indonesian copper concentrate.

“PT Amman Mineral Industri set the overriding design criteria to be proven technology that fulfills the strict international environmental standards. We are happy to help them to meet their sustainability goals by designing a copper smelter based on the most advanced technology in the world”, says Kalle Härkki, Head of Outotec’s Metals, Energy & Water business.
