Indonesia hikes export taxes for copper, zinc and iron - finmin

JAKARTA (Reuters): Indonesia's export tax rates for copper concentrate will rise to a range of 5% to 10%, according to a new regulation, as the government tries to push miners to process metals at home rather than export raw minerals.

The tax is part of the government's bid to drive smelter construction in Indonesia, with the aim of increasing domestic processing to get more value from the country's mineral resources. It also banned exports of raw minerals in June.
