JAKARTA, March 3 (Reuters) - Japan's Mitsubishi Material Corp resumed operations at Indonesia's main copper smelter on Thursday after fixing a minor problem, a spokesman said on Friday.
The company on Wednesday halted operations at the Gresik smelter, owned by PT Smelting, due to a technical issue.
PT Smelting is 60.5 percent owned by Mitsubishi Materials, while Freeport-McMoRan Inc's Indonesian unit holds 25 percent.
The outage affected Freeport, whose exports of concentrate have been halted in a dispute over mining rights.
