Metallic vs Non-metallic Minerals: Difference and Comparison

Metallic minerals contain metals in their chemical composition. They are associated with high luster and conductivity. In contrast, non-metallic minerals do not contain metals and have characteristics such as transparency, low conductivity, and a lack of metallic luster.

Key Takeaways

  1. Metallic minerals contain metals in their chemical composition, resulting in a lustrous appearance and high electrical and thermal conductivity.
  2. Non-metallic minerals lack metallic properties, exhibiting a non-lustrous appearance and poor electrical and thermal conductivity.
  3. Both minerals are vital resources, with metallic minerals used in manufacturing and technology, while non-metallic minerals serve various industries, including construction and agriculture.

Metallic vs Non-metallic Minerals

Metallic minerals contain metals such as iron, copper, gold, silver, and zinc. These minerals have a shiny, metallic luster and are hard and dense. Non-metallic minerals are minerals that do not contain metals. They are light in color and have a dull or earthy luster. Non-metallic minerals are less dense and less hard than metallic minerals.

Metallic vs Non metallic Minerals

Examples of metallic minerals are bauxite, iron, and tin; examples of non-metallic minerals are salt, marble, and coal.
