Answer 1

Instructions:

• Introduction
• Classification of minerals
• Ferrous and non-ferrous minerals

Answer:

• Minerals are naturally-occurring substances that have a definite chemical composition.
• Minerals are not evenly distributed. They can be identified based on their physical and chemical properties.
• Based on composition, minerals are classified mainly as metallic and non-metallic minerals.
  • Metallic minerals contain metal. They are hard and shiny. They are also good conductors of heat and electricity. Iron ore and bauxite are examples of metallic minerals.
  • Non-metallic minerals, on the other hand, do not contain metals.
  • Examples: Mica and gypsum
  • Metallic minerals are further divided into ferrous and non-ferrous minerals.
    • Ferrous minerals contain iron in them, whereas non-ferrous minerals do not contain iron.
    • Manganese, iron ore, and chromite serve as the best examples of ferrous minerals.
    • Gold and copper are non-ferrous minerals.
