The Pidgeon Process | Sovran White International Limited

The Pidgeon Process. The existing Magnesium Plant (and its proposed expansions) use (will use) the Pidgeon process. The basic raw material supply and magnesium production process is as follows: 1. Mining and crushing of the dolomite: The dolomite is mined and crushed by the supplier at the quarry, and delivered to the Magnesium Plant in 15-25mm granules. 2. Calcination of the dolomite: The

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 electrolytic methods of production, though above the 7 MWh/ton theoretical minimum..
