What are minerals - Extracting and buying and selling them

The place where minerals and minerals are located and accumulated naturally is called a deposit or mine. The deposits are named in various ways and based on different criteria such as the name of the discoverer, the place of discovery and the names of prominent historical figures or myths or the name of the mining company.

 

 

The origin of rocks and the study of economic geology are among the criteria for classification of deposits. This classification includes hydrothermal epigenetic deposits, hydrothermal associated granites, nickel-cobalt-platinum deposits, associated volcanic deposits, metamorphic reconstructed deposits, igneous carbonate carbonate Related are sedimentary deposits, sedimentary hydrothermal deposits and related stroblum ores.

 

Natural chemical compounds are solids that have a homogeneous and crystalline structure and are found in the earth and have variable physical properties. The science that studies and identifies natural and mainly solid mineral compounds such as quartz, feldspar, mica, gold and silver that ores are mined is called mineralogy. Mastery of mineralogy is very important for smelting metals and supplying raw materials to factories. On the other hand, these are the minerals that are the basis of the life of plants and animals and organisms in general, and by which the progress of science, technology and industry has been possible for human beings. The number of minerals on Earth is very large and they are classified based on their application and chemical properties.

These minerals are composed of elements with SiO2 and include quartz, feldspar, mica, talc, grona, tourmaline and olivine. (Magma is a combination of silica that cools outside or inside the earth by combining deep volatiles, metal oxides, and water vapor to form inner and outer igneous rocks, so these rocks are considered silicate). 90% of the earth's crust is made of silicates and contains 62.5% oxygen, 21.2% silicon, 6.5% aluminum and 2 to 3% of the elements iron, magnesium, sodium, potassium and calcium.
 

 

These minerals do not contain SiO2 in their composition and include carbonates such as (calcite, malachite and dolomite), sulfates such as (barite and gypsum), phosphates such as (turquoise and apatite), sulfides such as (sphalerite, pyrite, galena and Chalcopyrite), halogens such as (halite and fluorite), oxides such as (magnetite, hematite and chromite) and pure elements that contain metals and non-metals.

 

How to extract minerals includes the following 7 steps.

 

٭ First find minerals and measure their value and amount, to see if the stone is worth extracting?

 

٭ The amount and rank of ore is measured by performing mathematical estimates and calculations.
