"That 10% that there are four smelters, which is 20% four smelters . Which is 60-70% above the 15 smelters. So in total there are 28 smelters for bauxite, nickel, alumina, iron ore, "he said in Jakarta, Thursday, 11/07/2013). He hopes there are 15 smelters, of 28 smelters that can be completed prior to construction sites in 2015.

According to him, this development is time consuming, because the feasibility study for the construction of the smelter takes time for three years. "There's a smelting under two years. We expect 15 was completed before 2015. Everything should be built," he said.

Construction of the project in accordance with the mandate of Law. 4 of 2009 on Mineral and Coal Mining, processing and refining of minerals should be done in the country, resulting in increased value-added production and control of mineral commodities.

Currently there are 97 proposals are still in the stage of feasibility study, as many as 28 smelter which is expected to come perform the planned operation purification operations for the six main products that must go through purification (nickel, bauxite, manganese, copper, iron ore and iron sand).
