Förfarande för utvinning av magnesium. |
摘要 |
<p>Magnesium is recovered from a slag produced in a pyrometallurgical process and which contains magnesium oxide and other oxides. The slag is delivered, preferably in a hot state, to a reduction stage where the magnesium oxide is reduced and the magnesium vaporized. The reductant includes an alkaline earth metal in non-oxidic form, preferably calcium carbide. The vaporized magnesium is delivered to a condenser where it is condensed directly from the vapor state to a powder form.</p> |
