Kebutuhan dan Penyediaan Energi di Industri Smelter Tembaga
(Energy Demand-Supply in Copper Smelter Industry) 

Abstract

    Law No. 4 of 2009 on mineral and coal has pushed Indonesia to implement the advancement mineral’s value-added in the country, particularly for copper. Indonesian has copper reserves of 28 million metric tons that is enough to produce for the long term. In addition, PT Smelting now can process only one-third of the copper concentrate supply from PT Freeport Indonesia and PT Newmont Nusa Tenggara, therefore there is an opportunity to process copper concentrate in the country. Assuming that in 2015 the country will require new smelter industry with a production capacity of 350 thousand tons per year, in consequence the energy requirement for copper smelter industry will increase from currently at 0.50 million BOE to 1.08 million BOE in 2015. The power plant needed for the new smelter industry will have an installed capacity of 58.4 MW that supplied using gas turbine power plant.
