摘要
随着硫化镍矿资源日趋枯竭,高效开发占全球镍资源72%的红土镍矿日益迫切。介绍了世界红土镍矿资源的特点、国内外的开发现状,并阐述了其传统湿法生产工艺及进展;认为硫酸加压酸浸、堆浸和生物浸出等工艺因具有浸出率高、成本低、环境污染少等优点,是红土镍矿湿法冶金技术的重要发展方向。
As the nickel sulfide ore is exhausted, high efficient exploitation of nickel laterite ore, accounting for 72% of global nickel resources, becomes very urgent. The characteristics and exploitation status of nickel laterite resources were simply introduced in this article, and the traditional hydrometallurgical processes and development were also described. With the merits of high leaehing efficiency, low cost, and less environmental pollution, the high -pressured acid leaching, heap leaching and bioleaching methods had been considered as the main trend for hydrometallurgical technology of nickel laterite in the future.
