Pidgeon process

1999-12-9 · 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. Chemistry The basic chemical equation of this process is: Silicon and magnesia react to …

Magnesium - Essential Chemical Industry

2019-4-17 · Magnesium is the lightest structural metal used today, some 30% lighter than aluminium, and is generally used in alloys. Pure magnesium burns vigorously once molten, but magnesium alloys have higher melting points and are widely used in the automotive and aircraft industries.

Calcium Production by the Electrolysis of Molten …

The electrolyzers used to extract calcium from copper-calcium alloys at 0.5 to 3.0 kA were designed, manufactured, and utilized to study the process parameters more precisely. The pilot electrolysis device used to produce calcium from copper-calcium alloys at 12 to 15 kA was developed.

Magnesium: extraction-Metalpedia

Magnesium: extraction; Brife introduction; Magnesium is found in solution in sea-water (about 1.3 kg m-3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (MgCO3.CaCO3). Both of the two types of resources can be used as raw materials to manufacture magnesium metal.
