Natural minerals areaccumulations of organic or mineral origin, located in the earth's crust. Due to their special physicochemical properties, they are widely used in the most important spheres of human activity, for example, as feedstock or fuel resources. The existing classification identifies three of their main categories (depending on the state of aggregation in which these or other natural resources can be found): gaseous, liquid, and solid.
Natural minerals have a fairly simple classification according to their purpose. Allocate:
1. Ore substances.
2. Nonmetallic.
3. Combustible.
4. Hydromineral.
5. Mining and chemical.
6. Gemstone.
7. Construction.
The most valuable of all currently minedresources are coal, gas and oil. Such natural minerals produce most of the energy, both electrical and thermal, in all corners of the globe. Consider these resources in more detail.
Location of deposits of this type of usefulFossils almost directly depends on climate and geological conditions. Nevertheless, coal is found in the territories of many countries and on almost all continents. The origin of this natural resource is quite simple. This substance is a result of the natural processing of biomass deposits. The quality of coal is greatly influenced by parameters such as temperature, pressure, oxygen percentage and many others.
Gas
This substance is referred to as different terms.for example, natural or associated gas. This resource is a very efficient fuel used in everyday life and at work. From this colorless volatile compound, you can get not only heat and electricity, but also various types of plastics and synthetic fibers.
Oil
Like coal and natural gas, this substanceformed over a long time from the remains of animals and plants under special conditions. Such natural resources are of great importance for the economy of many countries of the modern world. During the processing of oil breaks down into fractions, of which in the future produce a huge amount of compounds and materials.
