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.The Cr 2 O 3 is blended with finely divided aluminum powder, charged to a refractory-lined container, and ignited.
Most chrome ore must be processed by the chrome processing plants. The main chrome ore processing method is gravity separation.

After the ore is extracted, it undergoes crushing and grinding to reduce its size and prepare it for further processing. The ore is crushed into smaller pieces using crushers and then ground into a fine powder using grinding mills. This process increases the surface area of the ore, facilitating chemical reactions in the subsequent steps.
Chrome ore beneficiation Most of the chrome ores around the world are beneficiated by gravity concentration techniques. A conventional chromite ore beneficiation process plant (Figure 3) consist of two sections: Communition (for preparing the material for the subsequent unit operations) Concentration (classification and beneficiation).
