About Chromite Ore

Chromite (FeCr₂O₄) is the primary source of chromium, a critical metal with extensive industrial applications. This dark, metallic mineral is predominantly found in ultramafic rocks and plays a vital role in metallurgy, chemicals, and refractory materials.

Key Properties of Chromite
  • High Melting Point (~2,180°C): Makes it ideal for refractory applications.
  • Resistance to Corrosion & Oxidation: Essential for stainless steel production.
  • Magnetic Weakness: Can be separated using magnetic separation techniques.
  • Density (4.5–5.1 g/cm³): Heavier than many silicate minerals, aiding in gravity-based beneficiation.

Major Uses of Chromite Ore
  1. Stainless Steel Production (80–90% of usage): Chromium enhances hardness, corrosion resistance, and durability.
  2. Chemicals & Pigments: Used in dyes, tanning agents (chromium sulfate), and chrome plating.
  3. Refractory Materials: Due to its heat resistance, chromite is used in furnace linings.
  4. Foundry Sands: Chromite sand molds withstand high temperatures in metal casting.
