hematite[矿物] 赤铁矿
We can extract iron from haematite by heating it with carbon in a blast furnace.
我们可以把赤铁矿和碳在鼓风炉内一起加热来提取铁。
On Earth, any natural metallic iron rusts in our wet, oxygenated environment, so we rely on iron oxides such as haematite to make steel.
在地球上湿润并充斥着氧气的环境中,任何天然的金属铁都会生锈。因此,我们依靠象赤铁矿中的氧化铁来制造钢材。
