As we all knew that there are four types of classification of minerals namely; Siliceous Minerals, nonmetallic minerals, metal ore minerals and the Gem Minerals.

This I introduce you the USES of them:

Uses of Siliceous Minerals:

1. Quartz crystals are used in making optical instruments. They are also use d in radio and electronic equipment because of their electrical properties. Quartz sand is used in the manufacture of glass and silica brick. In powdered form, it is an important ingredient of porcelain and paints. A rock composed of quartz (granite) is an important building material.

2. Feldspar is used to make porcelain and enamel. Feldspar forms a part of granite and is therefore a building material.

3. Mica is used for insulation in electrical equipment, wallpaper, and fireproof materials.

4. Powdered talc is used for paints, ceramics, and paper. It is also the major substance in talcum powder or what we commonly know as face powder.

Uses of Nonmetallic Minerals:

1. Calcite is used in the manufacture of cement and mortar. Chalk, a form of calcite, is used for fertilizers, for whitewash, and for writing on the board. Calcite is the main minerals in limestone and marble, both used for building materials.

2. Sulfur is used in the manufacture of sulfuric acid, explosives, dyes, insecticides, and fireworks. It is also valuable in vulcanizing rubber and paper making.
3. Salt is an important cooking ingredient and food preservative.

4. Borax is formed from Kernite and is extensively used in the manufacture of soap, enamels, Glass, and washing powders. It is used in welding, soldering, antiseptic, and preservative.

5. Gypsum is made into plaster of Paris and other building plasters.

6. Apatite contains phosphorus and is used for fertilizers.

7. Graphite is used in pencils.

Uses of Metal Ore Minerals:

1. Gold is used for coins, for jewelry, and in coating other ornamental objects.

2. Silver, a fine conductor of electricity, is used in photography. It is made into silverware like spoons and knives. Silver is also used in coins and jewelry.

3. Copper is used electric wires, making possible the manufacture of telephones, radios, televisions, and electric lights. Copper nails and sheets are used in buildings.

4. Iron and its principal alloy, steel, has innumerable uses in industry and in modern infrastructure projects.

5. Aluminum is used for roofing and in making planes, cars, and other transport vehicles. Cooking utensils made from aluminum conduct heat well, are very light, and do not tarnish.

6. Mercury is the source of the liquid mercury used in thermometers, in barometers, and in industry.

7. Titanium is used in paint pigments. It is also used as a structural metal since it is light but very strong.

8. Uranium, a radioactive metal, is a source of tremendous energy such as the isotopic U-235 in an atomic bomb. It can power nuclear submarines. Radioactive isotopes are used in medical research and in industry.

Uses of Gem Minerals:

1. They are valuable because of their durability, color, luster, and rarity. They are made into jewelry and other ornamental pieces.
2. Diamond, the hardest mineral, is very expensive and is used in industry as well as in jewelry.
