(A) Mica
(B) Bauxite
(C) Granite
(D) Potash

Choose the correct answer from the options given below:

(A), (C) and (D) only

Mineral Classification

Minerals are generally categorized into two types:

• Metallic Minerals: These contain metals in raw form (e.g., Iron, Copper, Gold, Bauxite).
• Non-Metallic Minerals: These do not contain metal substances and are often used in industries like construction, ceramics, and chemicals.

Analyzing the Options

• (A) Mica: A non-metallic mineral known for its insulation properties in the electrical industry.
• (B) Bauxite: A metallic mineral; it is the primary ore used to produce Aluminum.
• (C) Granite: A non-metallic mineral, specifically a common type of igneous rock used in construction.
• (D) Potash: A non-metallic mineral primarily used in the manufacture of agricultural fertilizers.

Conclusion: Since Bauxite is a metallic mineral, the non-metallic minerals in the list are (A), (C), and (D).
