Examples of nonmetallic minerals include sulfur, phosphorus, iodine, carbon, selenium, limestone, dolomite, gemstones, clay and mica. Nonmetallic minerals are minerals that do not contain metal. Physically, they are very volatile and have low elasticity. Chemically, they have high ionization energy.
Nonmetallic minerals are divided into four groups: metallurgical raw materials, chemical raw materials, construction materials and nonmetallic non-ore raw materials. Once extracted and processed, the final products are used in various industries, such as the building and construction industries.
Nonmetallic minerals are not always processed; some are used in their natural forms. Some examples of nonmetallic products include cement, sand, gravel, concrete, lime and glass.
