These, in turn, come in two sorts, limonite and saprolite.

又分为两种类型，褐铁矿和泥质矿。

Besides their ability to process limonite, HPAL plants are greener too, at least in some ways.

除了能够处理勒兰石之外，HPAL工厂在某面也更环保。

The method works with limonite and can directly produce the high-purity nickel needed in batteries.

该法适用于菱铁矿，并能直接生产电池所需的高纯度镍。

But most of the country's remaining nickel is locked up in deposits of limonite, which are not suitable for the RKEF process.

但该国剩余的大部分镍都锁定在赤铁矿沉积物中，沉积物不适合用于回转窑电炉工艺。
