摘要
阐述了氧化镍矿即镍红土矿的地质结构、分布和矿物组成差异等特点,提出开发和利用镍红土矿资源的重要意义。并详细介绍了当今世界工业处理镍红土矿主要方法的工艺流程及优缺点,重点对镍红土矿火法和湿法冶金工艺近年来的技术进步和未来的发展趋势进行了总结和预测。
This paper explains scientifically the most important properties of laterite nickel ore including geological structure, distribution and mineral composition difference, etc and restates the significance of laterite nickel ore. As the emphasis, the advanced technological process of laterite in the world and its advantages and disadvantages are detailed. It is summarized and forecast that the wet and smelting process of treatment of laterite advance and de velop in recent years.
