In order to provide guidance basisfor the development and utilization of an iron ore in Chi-na,a detailed process mineralogy study was carried out.The results show that the main useful iron minerals in an iron ore are siderite,followed by hematite,with the content of 29.59%and 22.78%,respectively.The main gangue minerals are quartz,with the content of 13.72%,followed by carbonate minerals calcite and dolomite,with the content of 7.27%and 12.51%,respectively,and the contents of other gangue minerals are less.The ore texture mainly includes massive structure and porphyritic structure.The ore structure main-ly includes granular structure,porphyritic structure,metasomatic residual structure,vein structure,phos-phorus flake structure and network structure.The siderite is mainly euhedral and semi-euhedral granular,which is closely associated with calcite and quartz.The hematite mainly exists in the form of primary ore and pseudomorphic ore.The process particle size of the useful iron mineral siderite in the ore is coarse-grained distribution,the distribution rate ofthe +0.07 mm fraction is 53.78%,while the hematite crystal size is fin-er,the distribution rate of the +0.07 mm fraction is 38.71%.
