Pidgeon Process For Extraction Of Metals

Pidgeon process - Wikipedia

21/09/2005· Pidgeon process. 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 …

Pidgeon Process - an overview | ScienceDirect Topics

While the Pidgeon process uses a small retort in general, the “Magnetherm process” uses a large, highly productive reduction–distillation furnace. This process is unique in that it charges alumina in addition to the dolomite and ferrosilicon. The addition of alumina lowers the melting point of the reaction products, thus allowing them to be removed as molten slag. The process is operated at 1500

23.2: Pyrometallurgy - Chemistry LibreTexts

The Pidgeon process is one of the methods of magnesium metal production via a high temperature (800-1400°C) process with silicon as the reducing agent (instead of carbon for iron extraction). The Pidgeon process involves the reaction of magnesium oxide with elemental silicon at high temperatures to form pure magnesium:
