Pidgeon Process an overview ScienceDirect Topics

The process is operated at 1500 °C under 25 mmHg. Impurities such as zinc and manganese are transferred into the magnesium product because of the high operating temperature. The purity of the product by the process is about 99.8% and low compared to that produced by the Pidgeon process.

Pidgeon process metallurgy Britannica

In magnesium processing: Thermal reduction. In the Pidgeon process, ground and calcined dolomite is mixed with finely ground ferrosilicon, briquetted, and charged into cylindrical nickel-chromium-steel retorts.A number of retorts are installed horizontally in an oil- or gas-fired furnace, with their lids and attached condenser systems extending out of the furnace.

Pidgeon process Article about Pidgeon process by

The existing operations produce magnesium using the Pidgeon process.However, the operations are licensed to expand output to 105,000tpa, which would make it one of the world's largest magnesium producers, and studies have been completed which augur well for a major expansion of its magnesium operations in a modular form largely by replicating the existing plant.
