Oct 11, 2013 The process is more complex when using first- and second-cut materials that contain cryolite (Na 3 AlF 6) and other fluorides, carbon, and alumino-silicates from the refractories. In this case, the pyrohydrolysis process would lead to dry hydrofluoric acid and the alumina and sodium oxide and the alumino-silicates would produce an inert slag.

German chemist who invented the alumino-thermic process (1905). Sometimes called the Goldschmidt reduction process, this operation involves reactions of oxides of certain metals with aluminum to yield aluminum oxide and the free metal.

The thermal diffusivity of five manganese ores and two quartzes was tested by applying the laser-flash method. The measurements show that the thermal diffusivity of manganese ore is strongly influenced by three factors: temperature, mineralogy and The Thermal Diffusivity of Raw Materials for Ferromanganese Production.
