优化铁精矿品位的意义与方法

The Significance and Methods of Optimizing the Iron Concentrate Grade

优化铁精矿品位一直是学术界和企业十分关注的问题。本文提出了铁精矿品位并非越高越好的观点，认为必须针对不同矿山矿石的不同性质和生产实际的不同技术、经济条件，优化铁精矿品位，才能取得企业的最佳经济效益和尽可能多的回收矿产资源。并介绍了独立矿山和采矿、选矿、烧结。

The optimization of the iron concentrate grade has always been attracting great attention in the acdemic circles and the related enterprises.The viewpoint is raised by the authors that it is not true that the higher the iron concentrate grade,the better.It is hold that only the different properties of various ores,the different technologies adopted and the different economic conditions in various mines are comprehensively considered,can the best economic results be achieved and the most mineral resources be recovered by optimizing the iron concentate grade.The calculation results of the comprehensive technical and economical models for independent mines and for the complex systems of mining mineral processing、sintering and iron-making are presented.
