magnesium processing | Techniques & Methods | Britannica

In order to lower reaction temperatures, industrial processes operate under vacuum. There are three principal methods, differing by their means of supplying heat. 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,
