Indonesian officials say there are no plans to withdraw the seven-month old ban on exports of unprocessed nickel ore and bauxite.
The country was the world's top exporter of nickel ore and a major bauxite producer until this past January, when the ban was issued in order to force miners to build smelters.
Last month, the government allowed several firms producing partially processed minerals such as copper concentrate to resume exports, although Indonesia's chief economic minister Chairul Tanjung says the same rationale does not apply to unprocessed exports of nickel ore and bauxite.
"Nickel is different because if you are smelting in Indonesia the added value is much higher than copper," says Tanjung. "Because of that it's a separate issue."
