提起铁矿人们马上就会想到它是钢铁工业的主要原料。铁矿的矿石矿物是个大家族,常见的就有十几种,但用于钢铁冶炼的铁矿石仅是磁铁矿石和赤铁矿石两种。镜铁矿是这个家族的成员之一,化学成分与赤铁矿相同,为 Fe_2O_3高价铁氧化物,三方晶系,与赤铁矿所不同的是结晶度高,化学性质较稳定,有时含钛、镁。物理性质:钢灰色,条痕为红色,片状、鳞片状集合体,晶面如镜,常有三角形花纹,金属光泽,硬度5.5-6,比重5-5.5,性脆,弱磁性。镜铁矿极少用于冶炼,是
People who lift iron ore will immediately think it is the main raw material for the steel industry. Iron ore ore minerals is a big family, there are a dozen common, but for iron and steel smelting iron ore is only two types of magnetite and hematite. Specular iron ore is a member of this family, the same chemical composition and hematite, Fe2O3 high iron oxide, trigonal system, and hematite are different from the high crystallinity, chemical stability is relatively stable, sometimes containing titanium ,magnesium. Physical properties: gray steel, streaks of red, flaky, scale-like aggregates, crystal surface as a mirror, often triangular pattern, metallic luster, hardness 5.5-6, the proportion of 5-5.5, sexual brittle, weak magnetic. Iron ore is rarely used for smelting, is
