2017-9-5 · The calcium metal can be obtained by processing calcium chloride, a by-product in the extraction of aluminum from anorthite. The production rate of titanium can be enhanced by scaling up the process to handle 69,000 tons of ilmenite per year. Alternatively, several reaction tubes can be employed to process the required ilmenite.

The Pidgeon process concerned with the production of magnesium metal at a temperature range from 1150 – 1300 °C in special retorts. While the production of magnesium metal by the magnetherm process is carried out in electric arc furnace under (inert atmosphere-vacuum) at a temperature range from 1500 – 1600 °C in the presence of slag.

Pidgeon Process - an overview | ScienceDirect Topics

J.W. Evans, in Encyclopedia of Materials: Science and Technology, 2003 5.2 The Production of Magnesium. Magnesium is produced by one of two routes: non-electrolytic ones (the “ Pidgeon process ” or “Magnetherm process”) and by the electrolysis of magnesium chloride dissolved in a mixture of molten chlorides. Steel hodes and graphite anodes are used in the latter.
