The Pidgeon process is one of the methods of magnesium metal production, via a silicothermic reduction. Practical production requires roughly 35–40 MWh/ton of metal produced, which is on par with the molten salt electrolytic methods of production, though above the 7 MWh/ton theoretical minimum. Visa mer The basic chemical equation of this process is: Si(s) + 2 MgO(s) → SiO2(s) + 2 Mg(g) (high temperature, distillation boiling zone) Silicon and magnesia react to produce silica and magnesium. Visa mer The Carbothermic route to magnesium has long been recognised as a low energy path to magnesium extraction.
