pidgeon process for extraction of metals

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 ...

magnesium processing Techniques Methods Britannica

This means that extraction of the metal from raw materials is an energy-intensive process requiring well-tuned technologies. Commercial production follows two completely different methods: electrolysis of magnesium chloride or thermal reduction of magnesium oxide through the Pidgeon process. Electrolysis once accounted for approximately 75 ...

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:

Extraction of Magnesium-

The extraction of magnesium mainly falls into two groups, i.e. electro-refining (for magnesite) and thermal reduction process (for dolomite). Brief introduction will be given in the following passage. Thermal reduction process is represented by Pidgeon process, named after its inventor Dr. Lloyd Montgomery Pidgeon. Pidgeon process consists of ...
