Research Progress on Separation Technology of Lean and Fine Refractory Iron ore in China
In order to promote the effective development and utilization of China's lean,fine and mis-cellaneous refractory iron ore,according to the characteristics and development difficulties of domestic iron ore resources,the current situation of refractory iron ore resources is described in detail.Beneficiation tech-nology and methods of siderite,limonite,micro-fine hematite,ultra-lean magnetite,complex polymetallic iron ore and related research results of mineral processing workers are summarized.Finally,the high-effi-ciency separation technology of refractory iron ore is prospected in order to promote the efficient develop-ment and utilization of lean,fine and mixed refractory iron ore in China.
