云南省是全国有名的有色金属王国,但它却蕴藏着十分丰富的铁矿石资源,初步查明,几个主要矿区的储量约××亿吨。目前除昆钢所属矿山在开采外,其它大部分尚来开发利用。因此,如何更好地利用云南铁矿石资源为四化服务,是摆在我省矿冶工作者面前的任务之一。云南铁矿石大部分属贫磁铁矿或弱磁性矿石。由于铁矿石性质的千差万别,决定了它的选矿方法也各不相同,可用重选、浮选、磁选或它们的联合流程。云南铁矿石到底用什么选矿方法回收是恰当的呢?因此开展云南主要铁矿石选矿试验研究,探讨云南铁矿石的利用问题,无疑对于充分、有效地利用云南铁矿资源,发展钢铁生产,加速四化建设是十分有意义的。
Yunnan Province is a well-known national non-ferrous metal kingdom, but it contains a very rich iron ore resources. It has been initially identified that the reserves of several major mining areas are about XX billion tons. At present, except for the mines owned by Kunming Mining, the majority of others are still under development and utilization. Therefore, how to make better use of iron ore resources in Yunnan to serve the four modernizations is one of the tasks before mine and metallurgy workers in our province. Yunnan iron ore is lean magnetite or weakly magnetic ore. Due to the vastly different nature of iron ore, it is determined that its beneficiation methods vary as well, with reselection, flotation, magnetic separation or their combined processes. Therefore, it is appropriate to carry out Yunnan iron ore beneficiation pilot study to explore the utilization of Yunnan iron ore, undoubtedly for the full and effective use of Yunnan iron ore resources, the development of iron and steel production It is of great significance to speed up the construction of the four modernizations.
