SUPPORTING DOWNSTREAM INDUSTRIES
Amman Mineral Industri (AMIN) was established on 24 March 2009 to build and operate purification facilities for copper concentrate (smelter) and anode-sludge (precious metals refinery – PMR) adjacent to the Batu Hijau mine in West Sumbawa. Currently, these projects are still in the construction, procurement, and installation stages, and AMIN has not yet commenced commercial operation. The smelter and PMR are considered to be National Strategic Projects under the coordination of the Coordinating Ministry for Economic Affairs of the Republic of Indonesia. When in operation, these downstream facilities will further encourage economic growth at the local and national levels.
EFFECTIVE AND ENVIRONMENT FRIENDLY PURIFICATION FACILITIES

The copper smelter now under construction will have an annual input capacity of 900,000 tons, sufficient to handle output from the Batu Hijau mine and the future output from the Elang project. The copper smelter and PMR facility uses state-of-the-art environmentally friendly technology.
