从红土镍矿中提取镍的技术研究现状及展望

The Current Situation and Prospects of the Process and Technology of Nickel Extraction from Laterite-nickel ore

随着世界上硫化镍矿资源日趋枯竭,开发利用红土镍矿是未来镍业发展的方向。本文介绍的红土镍矿处理工艺有火法工艺和湿法工艺,其中火法工艺和湿法工艺中的氨浸法、高压酸浸法存在明显缺点,而常压酸浸法有工艺简单、能耗低、操作易于控制、投资少等优点,将会有很好的发展前景。

With the sulfide nickel ore in the world resources dry up day by day,the development of laterite-nickel ore will be the main direction of nickel industry in future.Pyrometallurgy and hydrometallurgy are introduced in this article,pyrometallurgy,ammoniacal leaching and high-pressured acid leaching has obvious 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 w...
