JAKARTA, June 27 (Reuters) - Copper and gold miner Freeport Indonesia on Thursday launched its $3.7 billion copper smelter in Gresik, East Java, that has a total input capacity of 1.7 million metric tons of copper concentrate.

The smelter's output capacity will reach around 650,000 tons of copper cathode and 50 to 60 tons of gold, said Tony Wenas, chief executive of Freeport Indonesia, majority owned by the Indonesian government but operated by U.S mining giant Freeport McMoran.
