摘　　要：为改善田兴铁矿铁矿石的选别效果,对该地区新采出铁矿石进行了工艺矿物学分析。结果表明:矿石属于原生矿与氧化矿过渡带矿石,主要有价元素为铁,铁主要以磁铁矿和假象赤铁矿的形式存在;矿石主要结构有自形—半自形及他形粒状变晶结构、包含变晶结构、交代残余结构及交代假象结构等;矿石主要构造主要有条带状构造、条纹状构造、小揉皱状构造等;矿石中铁矿物主要呈条纹、条带状产出,粗细不均匀嵌布。研究结果可以为田兴铁矿工艺改造提供理论依据。To Improve the beneficiation efficiency of transition magnetite ore from Tianxing Iron Mine,process mineralogy analysis was conducted on the ore. Results indicated that,the ore belongs to primary ore and transition oxidized ore,main valuable element is iron,iron mainly exists in form of magnetite and hematite. The main ore structure are euhedral-hypidiomorphic and xenomorphic granular variable crystal structure,crystal structure,metasomatism type residual and metasomatic pseudomorphic structure etc. Main ore texture including banded structure,stripe like structure,small rub corrugation structure etc. Iron minerals mainly disseminated in strip,banding state. The results can provide theoretical basis for process modification of Tianxing iron ore.
