Process For Aluminothermic Production Of Chromium And

A process is provided for the aluminothermic production of low nitrogen containing chromium and chromium alloys, said chromium alloys comprising about 80 chromium, about 20 nickel and less than 0.005 nitrogen, said alloys being especially desirable for use as master alloys in production of super alloys where levels of nitrogen imparted by chromium alloying elements are critical.

Lumpy Chrome Ore Processing Steps

The aluminothermic process begins with the roasting of fine ore, soda, and lime in air at 1,100 C 2,000 F. This creates a calcine containing sodium chromate, which is leached from the insoluble gangue and then reduced and precipitated as Cr 2 O 3 .

3 Electrolytic Chromiummetal Production High

Similar considerations apply to the aluminothermic process. Metallic chromium recovered as floor sweepings can be reintroduced into the process stream at the leaching step. The vacuum-degassing process itself results in production of gaseous stack emissions, largely consisting of carbon monoxide, although these are insignificant in relation to ...

Chromium Ore An Overview Sciencedirect Topics

A process was developed in 1893 by Henri Moissan to produce ferrochromium in an electric furnace by the reaction of chromium oxide and carbon. In 1898, the German chemist Hans Goldschmidt produced chromium by the aluminothermic reduction of Cr 2 O 3. Other advances have included the production of chromium by aqueous electrolysis in 1954.
