How many minerals are there? As of November 2018, the International Mineralogical Association had recognized about 5,400 minerals. About 30 to 50 new minerals are described and one or two minerals are discredited each year.

Minerals are also important for making enzymes and hormones. There are two kinds of minerals: macrominerals and trace minerals. You need larger amounts of macrominerals. They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur.

Types of minerals

• Native elements. eg. Gold, Silver, Mercury, graphite, diamond.
• Oxides. eg corundum (incl. sapphire), hematite, spinel.
• Hydroxides. eg. Goethite, brucite.
• Sulfides. eg. Pyrite, galena, sphalerite.
• Sulfates. eg. Baryte, gypsum.
• Carbonates. eg. Calcite, magnesite, dolomite.
• Phosphates. eg.
• Halides. eg.

Minerals include calcium and iron amongst many others and are found in:

• meat.
• cereals.
• fish.
• milk and dairy foods.
• fruit and vegetables.
• nuts.

The two principal types of natural aggregate are crushed rock (limestone, igneous rock and sandstone) and sand and gravel. In addition to land–won sand and gravel, significant quantities are produced by marine dredging.

Typical construction minerals are aggregates (sand, gravel, and crushed natural stone), various brick clays, gypsum, and natural ornamental or dimension stone. The demand for construction minerals is generally high.
