摘要
简单介绍了国内镍钼矿的经济价值、主要分布地区及矿物组成特点。指出了对镍钼矿采用传统焙烧-浸出的方法将带来严重的环境污染问题,并对镍钼矿现阶段主要的湿法冶金方法进行了简要的评析,指出镍钼矿的常压氧化浸出、加压氧化浸出、生物浸出中各类方法的优点与缺点。提出了镍钼矿湿法冶金工艺是镍钼矿冶炼的发展方向。
The economic value of domestic Ni-Mo ores and its main distribution area and mineral composition characterization were introduced.It is pointed out that conventional nickel-molybdenum roasting-leaching method will bring serious environmental pollution problems.The latest main hydrometallurgical methods of Ni-Mo ores was analyzed.The advantages and disadvantages of various methods which contain of the normal pressure leaching、high pressure leaching and bio-leaching was described.It＇s put forward that the hydrometallurgical process is the development of Ni-Mo ores smelting.
