The former with low Ni content and high Fe content which is suitable to high pressure acid leaching.
前者铁含量高、镍含量较低，宜采用高压酸浸湿法冶金工艺处理；
This procedure (high pressure acid leaching), which is not yet used frequently, is especially energy-saving compared to the classical smelting in a rotary furnace.
这种还没有被广泛应用的矿石冶炼方法（高压酸冶炼方法）可较传统的熔炼方法具有节能的特点。
