Which one of the following is a non- metallic mineral?

Correct option is D

• Limestone is a non-metallic mineral. It is primarily composed of calcium carbonate (CaCO₃) and is commonly used in construction, manufacturing, and agriculture. Non-metallic minerals do not contain metal elements and are typically used for industrial or agricultural purposes. Limestone is used in the production of cement, as a building material, and as a soil conditioner.

• Non-metallic minerals are minerals that do not contain metal in their composition and are mainly used for their physical properties, such as in construction or as industrial raw materials.
• Limestone is used in industries such as cement production, glassmaking, and water purification.
• Lead, Copper, and Tin are all metallic minerals, meaning they contain metal and are primarily extracted for the production of metal-based products like wires, pipes, and alloys.

• Lead is a soft, heavy metal used in batteries, shielding from radiation, and in certain types of glass.
• Copper is a widely used metal, especially in electrical wiring and plumbing due to its excellent conductivity.
• Tin is primarily used in making alloys such as bronze and in coating other metals to prevent corrosion.
