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.

Pidgeon process | Detailed Pedia
The Pidgeon process is a batch process in which finely powdered calcined dolomite and ferrosilicon are mixed, briquetted, and charged in retorts made of nickel-chrome-steel alloy. The hot reaction zone portion of the retort is either gas fired, coal fired, or electrically heated in a furnace, while the condensing section equipped with removable ...

Motivated by low investment cost, low cost labour and lax environmental standards primary Mg capacity rapidly shifted to China through the broad based but small scale application of the Pidgeon process. However, in that same period China itself has developed into a more sophisticated and developed nation no longer offering those same drivers.

The process that is used in China to extract the magnesium from the oxide is called the Pidgeon Process. This process starts with mined dolemite. The dolemite is heated to nearly 1200 degrees in a large rotational furnace. The heating process bakes off much of the gasses and impurities held in the dolemite. From there the dolemite is crushed ...

The Pidgeon process was long thought to be uneconomic and obsolete. The Chinese have used the advantages of excellent raw material, location, large skilled labor supply, and low capital costs to produce magnesium by this process. The Chinese magnesium is being sold at the lowest prices in the world and lower than aluminum on a pound for pound ...

Abstract: Pidgeon process is used by more than 300 plants in China to produce magnesium (Mg) metal. Fluorite, ranging 2-3%, is often mixed in raw materials to catalyze the Mg production. The Mg slag from the production then contains F of several mass percent. When the Mg slag is used in construction or treated for recycling, possible F ...
