典型多金属型铁锰矿高温矿相重构与铁酸锰材料制备研究

在典型金属矿产资源铁锰矿综合利用的过程中，锰、铁等成分易生成强磁性复合铁酸盐，导致其综合利用过程中有价组元分步分离难度大。本研究改变传统铁锰矿资源锰、铁需预先分离后分别利用的认识，提出铁锰矿高温矿相重构同步回收锰铁有价组元并制备铁酸盐材料的技术思路。本文对铁锰矿冶金材料化加工过程中的矿相重构原理、新生相颗粒尺寸表征、矿相重构-磨选机理、分选磁性样品的性能进行了综述与分析。本次课题为"资源-冶金-材料一体化"研究的典型案例，可为金属矿资源的短流程材料化高值利用提供新的途径，也可以为其它类型低品质资源的综合利用提供技术借鉴。

High-temperature Phase Reconstruction Process of Typicalpolymetallic Ferru-ginous Manganese Ores and Preparation of Mnferrite Material

During the existing comprehensive utilization methods of ferruginous manganese ore, it's found that the spinel-type composite ferrites with strong magnetism are readily generated from the Mnand Fe constitutes resulting in the poor separation of the valuable metals. In this study, thetraditionalseparationof Mnand Feischanged, andtheextraction of valuable components and preparation of manganese ferrites synchronously from the ferruginous manganeseore by mineral phase reconstructionis put forward. The principle of mineral phase reconstruction, the particle size characterization of new phase, the mechanism of mineral phase reconstruction and grinding and separation, and the performance of separated magnetic products are reviewed in this work. This study is a typical case research of mineral-metallurgy-materials integration research, which can provide a short process for the high-efficiency utilizationof metallic mineral resources, and it also provides a technical reference for the comprehensive utilization of other types of low-grade polymetallic ore resources.
