Mineral Minerals

Useful fossils are natural entities that man extracts from the subsoil or from the surface of the Earth and uses for various purposes.

The largest group of minerals consists of metal ores composed of metals (jeles, copper, zinc, gold, silver, etc.) and various mixtures (general ore samples). Depending on metal content, ores are divided into rich and poor. For example, a brown iron is a poor iron ore and a magnetic iron is rich. It is the high iron content of the magnetic iron that explains its magnetic properties.

The next mineral group is minerals♪ These include peat, brown and stone coal, oil and natural gas. Naphth is a remarkable mineral that makes many useful things, such as gasoline, kerosene, machine oils, plastics, artificial rubber, synthetic fibers, paints, paws, medicines, asphalts and many others.

The third group consists of building minerals - granite, marble, limestone, glin, sand, hips. Granite is a complex mineral that consists of three minerals, a field scape, a quartz and saliva. Granite and marble are used in the streets of buildings, subway stations. The famous wizard was formed from the cancer of ancient marine molluscs. Plits cut out by a limestone orchestra have a beautiful deplorable surface and are also used in the streets of buildings. Glina and sand are needed to make cement, concrete, brick, and hipps are needed to produce correlated mixtures.
