Smelters and coal-fired power plants burn to process nickel ore into material for batteries and steel.

冶炼厂和燃煤发电厂燃烧，将镍矿石加工成电池和钢铁的材料。

Indonesian nickel ore, in contrast, is uneconomic unless it is processed near where it was mined.

相比之下，印度尼西亚镍矿除非在开采地附近进行加工，否则就不经济。

Nickel prices soared to five-year highs after the Indonesian government brought forward a ban on exports of nickel ore to December, two years earlier than it had proposed.

在印尼政府将镍矿石出口禁令提前两年至12月后，镍价飙升至5年高点。
