We produce both vertical and horizontal retort to reduce the magnesium or calcium metal by Pidgeon process technology. The retort is produced by our hot mold horizontal Centrifugal Casting Machine classified to diameters range from 300mm to 800mm with lengths range from 3,000mm to 3,500mm.
Pidgeon's process of thermally reducing magnesium oxide with silicon in externally fired retorts was introduced. 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 ...
A broad technology comparison of carbothermal magnesium production with present technologies has not been previously presented. In this paper a comparative analysis of CSIRO's MagSonic™ process is made with the electrolytic and Pidgeon processes.

Explains the method of magnesium melting by fluoride-free mineralizers instead of fluorite, which is an innovative discovery of the author's group. This open access ...
3.1.2 Basic Principles of Pidgeon Process. Calcined dolomite is the most remarkable raw material to use as magnesium source in the Pidgeon process and, it theoretically contains 58.2 mass% CaO and 41.8 mass% MgO, respectively. 6 The fundamental principle of the Pidgeon Process is the reduction of magnesium from calcined dolomite by using silicon (or any silicon containing material like ...
The key to this process relies on the utilization of slag and aluminium, in addition to ferrosilicon, for the reduction of magnesium oxide at higher temperatures, 1700 to 1750oC. Thus, the vapour pressure of magnesium is much higher, at about 0.85 atm. This process has higher productivity than the Pidgeon process.

Currently, 85% of Mg comes from China. The Western Magnesium process begins with mined dolomite (calcium-magnesium carbonate), which is crushed and calcined (thermal decomposition) to make MgO. The MgO is combined with ferrosilicon, a reductant that is also used in the Pidgeon process, and a catalyst, and formed into briquettes.

This microwave Pidgeon process with an antenna configuration made it possible to produce Mg with an energy consumption of 58.6 GJ/t, corresponding to a 68.6% reduction when compared to the ...
There are two main magnesium refinement processes being used in the world today. 85% of that is done through the Pidgeon process which results in a less pure magnesium and 15% is done through the electrolysis process which creates a purer form of magnesium. Our technology overcomes the inefficiency of current production methods that require ...
Abstract. Thermochemical equilibrium calculations indicate the possibility of considerable fuel savings and CO{sub 2} emission avoidance in the three steps of the Pidgeon process: (a) calcination of dolomite; (b) production of ferrosilicon from quartz sand, coal, and iron oxide; (c) silicothermic reduction of calcined dolomite by ferrosilicon to magnesium.
The Pidgeon Process, developed by Dr. Lloyd Pidgeon, is both an energy and labor-intensive form of thermal reduction. In this process, closed-end, nickel-chromium-steel alloy retorts are filled with a mixture of calcined dolomite ore and ferrosilicon, which are …
We want to connect the metallurgists who have knowledge to the metallurgists who need it, to bring together metallurgists with different perspectives so they can understand each other better, and to empower everyone to share their knowledge.
magnesium processing, preparation of magnesium ore for use in various products.. Magnesium (Mg) is a silvery white metal that is similar in appearance to aluminum but weighs one-third less. With a density of only 1.738 grams per cubic centimetre, it is the lightest structural metal known. It has a hexagonal close-packed (hcp) crystalline structure, so that, like most metals of this structure ...
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 ...
Trust is an important factor in risk management, affecting judgements of risk and benefit, technology acceptance and other forms of cooperation. In this book, the world's leading risk researchers explore all aspects of trust as it relates to risk management and communication. The authors draw on a wide variety of disciplinary approaches and ...
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 is a widely used vacuum silicothermic reduction process to produce primary magnesium (Mg) metal and, the process was developed by Lloyd Montgomery Pidgeon in the beginning of 1940s in Canada. 1,2 L. M. Pidgeon was born in 1903 in Ontario, Canada (Figure 3.1). He graduated

Attempts were made to prepare the rare earth metals, Sm, Eu, and Gd with total impurities of less than 0.1 ppm. Methods of separation, reduction, and purification were: ion exchange, dry fluoride preparation, metaliothermic reduction, vacuum distillation, zone refining by induction heat, and electron beam melting.
