【摘要】 <正> 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。更多还原

【Abstract】 The main purpose of the research is to make full use of Yunnan iron resources. We have studied the mineral properties and magnetic properties of the yunnan iron ores. The results how that most iron ores are characterized with weak magnetic properties. only a small part has strong magnetic properties and some arc complex ores. Experiments have shown the best passible processes in the beneficiation of the various Yunnan iron ores. It is suggested that the development of iron and steel industry in yunnan be based on the utilization of the iron resources in the province itself.更多还原
