Answer:
A mineral is a naturally occurring, inorganic solid with a characteristic chemical composition and an orderly crystal structure. Metallic minerals contain metals or can provide metals when processed; examples include iron ore, copper, and gold. Nonmetallic minerals do not yield metals and include quartz, gypsum, and salt. Some minerals are valued as gemstones because of their beauty and durability, such as diamonds. Minerals are important resources used in construction, electronics, jewelry, and many other products.
