Non-metallic minerals are natural substances that do not contain metals and are primarily used for their physical and chemical properties. Common examples include limestone, gypsum, and clay. These minerals are essential in various industries, such as construction, agriculture, and manufacturing, due to their versatility and abundance. Unlike metallic minerals, non-metallic minerals are not typically used to produce metals. Instead, they are often utilized in products like cement, fertilizers, and ceramics. Their extraction and processing are crucial for economic development, making them significant resources in many regions around the world.
