• Pidgeon process Wikipedia

    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.

    In magnesium processing: Thermal reduction. In the Pidgeon process, ground and calcined dolomite is mixed with finely ground ferrosilicon, briquetted, and charged into cylindrical nickel-chromium-steel retorts.A number of retorts are installed horizontally in an oil- or gas-fired furnace, with their lids and attached condenser systems extending out of the furnace.

Si(s) + MgO(s) ↔ SiO2(s) + Mg(g) (high temperature, distillation boiling zone) 2. Mg(g) ↔ Mg(liq, s) (low temperature, distillation condensing zone) Silicon and magnesia react to produce silicaand magnesium. Though, according to Ellingham diagrams, this reaction is thermodynamically unfavorable, in accordance with the Le Chatelier's principle of equilibriums, it can still be driven to the right by continuous supply of heat, and by removing one of th

    Abstract: Pidgeon process is used by more than 300 plants in China to produce magnesium (Mg) metal. Fluorite, ranging 2-3%, is often mixed in raw materials to catalyze the Mg production. The Mg slag from the production then contains F of several mass percent. When the Mg slag is used in construction or treated for recycling, possible F pollutions are of concerns.
