magnetite ore
3.The ore deposit can be named as subvolcanic hydrothermal garnet-diopside-magnetite deposit.
5.Large amount of Mg2+entered in octahedron sites of magnetite of pellet of Hangchow stael works during induration period has been examined by use of Mossbausr effect which was ascertaind the mechanism of Mgo concentrated into iron oxide compound and changed the mineral constitasnts of iron ore agglomeratesfrom avove investigation the effect of Mgo on the metallurgical properties of iron ore agglomerates was abtained.
7.Abstract: According to the composition, the thermal-water sedimentary rocks of Yinmin Formation in the Dongchuang copper ore field can be divided into nine types, of which skarnoid, cupric magnetite carbonate, paracontemporaneous breccia formed in thermal water processing are confirmed and named in this study.
