MCQ Detailed View

Chromium is an important transition metal widely used in stainless steel production, metal plating, and chemical industries. The main source of chromium is the ore called Chromite, which is chemically represented as FeCr₂O₄. Chromite is an iron chromium oxide and is considered the most important and abundant ore for extracting chromium.

Chromite occurs naturally in ultramafic and mafic rocks, and is typically mined through open-pit or underground mining methods. Its high melting point and resistance to corrosion make it valuable in industrial applications. The metal obtained from chromite is used in stainless steel, refractories, pigments, and chrome plating.

Other options listed in the MCQ are not related to chromium extraction:

• 
  

  Argon is a noble gas used in welding and lighting, not an ore.

  
  


• 
  

  Mirage is not a mineral or chemical substance.

  
  


• 
  

  Diamond is a form of carbon used in jewelry and cutting tools, not a source of chromium.

  
  

The extraction process from chromite involves reduction with aluminum or silicon, producing pure chromium or ferrochromium alloys for industrial use. Understanding the identification of metal ores like chromite is a key concept in inorganic chemistry and helps students recognize the practical applications of metals in daily life and industry.

In summary, Chromite is the primary ore of chromium, essential for industrial purposes and metallurgical applications. Recognizing chromite and its properties is an important topic in chemistry, especially for students learning about metal ores and their uses.
