· the largest magnesium raw material production country in the world. Its annual output of Magnesium reaches 80% of that of the whole world. Most of Chinese magnesium enterprises employ silicothermic reduction process—Pidgeon process, which produces huge amount of the reduction slag. The magnesium slag is not only
production of magnesium. 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 ...
· The reason for the extensive use of the Pidgeon Process is due to the shift in production to the coal-rich provinces in north-central China where labor and energy costs are significantly lower than in other magnesium producing …
Since this production method does not produce the most ideal magnesium for anode production, American Carbon only selects the most qualified ingot for production of anodes. One of American Carbon biggest challenges is educating customers as to the strengths and weaknesses of the Pidgeon Process versus the Dow Process.
