Mineral Processing Test and Study on Chromite in Indonesia. This chromite project in Indonesia, with the Cr2O3 of 9%, was classified as poor chromite. The main metallic minerals in the chromite ore included chromite, magnetite, a little ilmenite and ferrous manganese ore. The main gangue minerals included quartz, calcite and chlorite.


The conversion of chromite to chromia proceeds via Na 2 Cr 2 O 7, which is reduced with sulfur at high temperatures: Na 2 Cr 2 O 7 + S → Na 2 SO 4 + Cr 2 O 3. The oxide is also formed by the decomposition of chromium salts such as chromium nitrate, or by the exothermic decomposition of ammonium dichromate. (NH 4) 2 Cr 2 O


Transcribed image text: Pure chromium metal is prepared from the ore chromite. The ore is converted into sodium dichromate, Na2Cr207, which is then reacted with carbon to form the oxide Cr2O3. Reaction of the oxide with aluminum metal yields the chromium metal Cr2O3 + 2 Al → Al2O3 + 2 Cr If you reacted 50.0 g of Cr203 (molar mass = 152.0 g/mol) with 20.0 g of aluminum (molar mass = 27.0 g ...
