This paper is a contribution to the theoretical and quantitative understanding of the processes for the production of magnesium metal by metallothermic process in vacuum (Pidgeon Process). In the present study, effects of reductant type and amount were investigated. CaC 2 is a low-cost alternative to FeSi (ferrosilicon) which is the common reductant in the Pidgeon Process. CaC 2 slightly ...
Since early 2014, the Shemaco project has been under development as a joint venture between Aramico and London Tonnage Limited, with the aim to build on the group's technical understanding and patented process in order to develop the Magnesium Industry for international export.
Pidgeon, working with one technical graduate, achieved commercial development of a process to produce magnesium by reducing calcined dolomite with fcrrosilicon, i.e. the silicothermic process.

The techno-economics of the Mintek Thermal Magnesium Process (MTMP) has been revisited and at current market conditions, and for operation in South Africa, it competes favourably with China's Pidgeon plants. Ideally, the process should be operated for at least 12 months at an intermediate scale (5000 t Mg/annum) before
2012. Chinese Pidgeon process has been improved by considering the productivity and carbon footprint. After August 2012, infrastructure, engineering, procurement, construction and commissioning has been conducted and production started in September 2015. By using different technologies of an improved Pidgeon method, Primary Mg production

May 25, 2017· The magnesium industry has seen massive disruption in the last 10-20 years, Andrews said. "China started using cheap labour and coal power using the Pidgeon process for magnesium metal and nearly all the big international companies died and billions of dollars were written off."
This open access book introduces the magnesium resources in the world and the layout of this industry, the harmless handling/recycling of magnesium slag, and the process of magnesium silicothermic reduction (Pidgeon process) to produce the slag.
Electrolytic producers in the west have been replaced by Chinese pyrometallurgical production via the the Pidgeon process; The capital cost for Australia Magnesium (AM) Process using an electrolytic route was estimated to be $10,000/tonne Mg, while the capital cost for the Pidgeon process was estimated to be $3,000/tonne Mg in 2008 ...
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 ...
Jun 30, 2014· In the past 40 years, Chinese Pidgeon process was a great improvement, the energy consumption, ferrosilicon consumption, and the ratio of raw material to rough magnesium in reduction process improved significantly, especially the application of regeneration heating technology in the heating furnace decreased the energy consumption to a great ...
Nov 24, 2018· The MINTEK process is a silico-thermic process operating at atmospheric pressure and at a temperature of about 1600-1800degC. Magnetherm process was developed in 1950s and served as an advanced version of Pidgeon's process. In this process, magnesium extraction is carried out in an AC submerged arc Furnace DC arc furnace technology led to ...
Magnesium Pidgeon Process Smelter, Mag Alloy Plant, Downstream Mg Components ... Brine based projects worldwide have underperformed and proved unprofitable. Chinese magnesium brine projects, existing and planned, have all floundered (or likely to fail) and others brine-based in the West closed down. ... marketing, financial, and the technical ...
Mg production process used in China at present. It is named Pidgeon process after his inventor, the Canadian chemist Lloyd M. Pidgeon. Figure 3 shows an overview of the process steps. Due to its abundant deposits, the raw material for Mg production in China is magnesium-calcium carbonate dolomite (MgCO 3·CaCO 3). Thus, the first production step

The estimated operational costs to produce Mg are ∼$2.46/kg. At this cost, the process without a solar thermal input is economically tantalizing vis à vis the current commercial processes for producing Mg, and its CO 2 emission level is 46% lower than that of the Pidgeon process, currently the predominant method for producing Mg.
Pidgeon process. 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 …
Jun 30, 2014· 10%· In the past 40 years, Chinese Pidgeon process was a great improvement, the energy consumption, ferrosilicon consumption, and the ratio of raw material to rough magnesium in reduction process improved significantly, especially the application of regeneration heating technology in the heating furnace decreased the energy consumption to a great ...
Sep 01, 2020· The Pidgeon process is a thermal reduction process that extracts magnesium from calcined dolomite under a vacuum pressure of 10 Pa and a temperature of 1100 ∼ 1200 °C by the ferrosilicon as a reducing agent and calcium fluoride as a mineralization agent in …
the growth in Chinese magnesium production capacity has led to the almost complete decline of western magnesium and the electrolytic route. China's adoption of the Pidgeon process (thermal route) enabled it to be the world's biggest producer, due to the relative easiness, versatility, and reduced capital cost of this process.
Dec 05, 2017· They are projecting magnesium production costs of $1400 to $2400/metric ton ($.64/lb or $1.09/lb). The Mag One process was initially developed by Dr. James Blencoe, formerly from Oak Ridge National Laboratory (ORNL). The process uses a carbonization process to convert a low-cost magnesium silicate ore (Serpentine) to magnesium carbonate.
