一种重要的精炼方法。在氧化精炼过程中,粗金属中易被氧化的杂质同氧化合后,转入炉渣或为气体逸出,从而获得工业纯金属。氧的来源可为空气、工业纯氧或 其他氧化剂。可以直接吹入液态金属,或通过渣层 向熔池扩散。氧化剂有多种,如炼钢时加入的铁矿石、精炼有色金属时加入的硝酸钠等。氧化精炼广泛用于炼钢和重金属(如铜、铅、锡等) 的精炼。
工业上去除杂质元素的方法主要有氯化精炼法和氧化精炼法。
The methods of removal such impurities as al and Ca include chlorination and oxidation refining process industrially.
钢铁制造商还广泛使用氧或富氧空气来影响同除碳和其它氧化反应相联系的化学精炼和加热。
Steel and iron manufacturers also extensively use oxygen or oxygen-enriched air to affect chemical refining and heating associated with carbon removal and other oxidation reactions.
