United States Patent 4169722 Where the exothermic heat of reaction of the oxide ore is insufficient by far to raise the temperature of the reactants to give molten slag and metal phases (i.e. although exothermic the reaction is not autothermic), the conventional methods of aluminothermic reduction are clearly not
Aluminothermic reaction RevolvyAluminothermic reaction An aluminothermic reaction using iron(III) oxide. The sparks flying outwards are globules of molten iron trailing smoke in their wake. Aluminothermic reactions are exothermic chemical reactions using aluminium as the reducing agent at high temperature. The process is industrially useful for production of alloys of iron.[1]roasting and leaching process for chromiumaluminothermic reaction process for chromium ore. Roasting And Leaching Process For Chromium. For the production of ferrochromium the chromite ore (FeCr 2 O 4) is reduced with either aluminium or silicon in an aluminothermic reaction and for the production of pure chromium the iron has to be separated from the chromium in a two step roasting

Principles of Aluminothermic Welding Railtech UKThere is more than 100 years between those two pictures regarding the same Aluminothermic welding process. In 1893, experimentations on Aluminothermic reactions for the production of high purity Chromium and Manganese started. By the end of the 19th century this technology had been applied to the rail industry to weld two pieces of rail together.HighPurity Chromium Metal: Supply Issues for GasTurbine The geologic sources of chromium are essentially mixtures of spinels of the ideal form RO·R 2 O 3 (e.g., chromite is FeO·Cr 2 O 3), although a more accurate representation of an ore source would be (Mg,Fe)Cr 2 O 4 with silica and alumina gangue materials. The refining processes for chromium metal have been thermodynamically defined by their spinel origins.
