Abstract:With the sulfide nickel ore in the world resources dry up day by day, the development of laterite
- nickelorewill be themain direction of nickel industry in future. Pyrometallurgy and hydrometallurgy are
introduced in this article, pyrometallurgy, ammoniacalleaching and high- pressured acid leaching has obvi
ous disadvantage. Craft simply , energy consumption low, the operation easy to control, investment low
are the merits of the constant- pressured acid leaching.It is belived that constant- pressured acid leaching
will be have very good prospects for development.
