main economic resources, is used all over the world due to the presence of valuable minerals that can be exploited. In this article, the concept of mine and how it is formed, how to find and extract mines, different types of mines in the world and Iran, and its impact on the global economy will be discussed.”
A mine is a place that is accumulated from all kinds of metal minerals, stones and rare materials, which exist under the surface of the earth and sometimes on the surface of the earth. These materials are economically exploitable and are used to produce materials such as metals, fossil fuels, chemical products and other uses.
The history of the discovery and exploitation of mines goes back thousands of years. Since ancient times, humans have used mines to extract metals and precious stones. In the early times, mining was mostly done on the surface and using simple tools. With the development of technology and mining tools, the methods of exploitation of mines also evolved.
In ancient history, many cultures used mines to extract metals such as gold, bitumen, silver and copper. For example, Egyptians extracted precious stones using simple tools such as adzes and chisels. In India, mines were used to extract diamonds and jewels. Also, in ancient times, exploitation of mines for iron extraction was also common.
Structure of mines: concept and components
The concept of mine structure
Mine structure refers to all the components in a mine. These components include rock, sediments, volcanoes, soil, and other materials that exist below the surface of the earth and sometimes on the surface of the earth. These components are naturally obtained and can form ore.
Structure components of mines
The structure of mines consists of various components, which are explained below for each of these components.
Mine rock or mine soil refers to materials that contain valuable minerals such as gold, silver, copper, etc. According to their type and characteristics, these minerals can be used as raw materials in various industries.
Sediments are substances that are obtained as sediment in water or sediment in soil. These materials include materials such as sand, gravel, silt and other materials that are used as raw materials in industries such as construction, chemical industries, etc.
Volcanoes are different structures that are used due to the presence of minerals in them. These structures include materials such as lava, volcanic sediments, and volcanic rocks.
Soil is the material that exists on the surface of the earth. These materials include fine particles such as organic and mineral materials, water and air and other materials that are mixed in the soil. Soil is used as an important resource for agriculture and horticulture and also plays an important role as a place for plants to grow and maintain biodiversity in the environment.
The formation of mines
Mine formation is divided into two types: surface and underground. Surface mines are formed due to the presence of minerals on the surface of the earth. On the other hand, underground mines are formed due to the presence of minerals in underground parts.
Types of mines
The shape of the deposit refers to the shape and distribution of minerals inside the deposit. In this article, the types of deposits will be investigated.
In the form of a base deposit, the minerals are in the form of a large block. This form of deposit is mostly seen in underground mines, and to extract minerals from inside the block, the block must first be divided into smaller pieces.
The shape of the veins
In the vein deposit form, the minerals are in the form of narrow and long veins that are cut from the rock. This form of deposit is mostly seen in underground mines, and in order to extract deposit materials from inside the veins, these veins must be opened using special devices that cut small pieces of rock.
In the form of dispersed deposits, minerals are dispersed in the form of small particles on the surface of the earth or in groundwater. This form of deposit is mostly seen in open pit mines, and methods such as crushing and screening are used to extract deposit materials from inside the particles.
In the form of a mass deposit, the deposit materials are located in the form of large and uneven masses on the surface of the earth. This type of deposit is mostly seen in open pit mines, and to extract the deposit materials from the piles, the piles must first be divided into smaller pieces.
The shape of the minerals
In the mineral form of ores, minerals are in the form of small ores that are scattered inside the rock. This mineral form is mostly seen in underground mines, and to extract minerals from the ores, these ores must be opened using special devices and then the minerals are separated from the ores.
In the mineral paste form, the minerals are in the form of a dilute paste in water or a solution. This form of mineral is mostly observed in the mineral that exists as a solution in water or another solution. In order to extract minerals from the pulp, it is necessary to first separate the pulp from non-mineral materials and then separate the minerals from the pulp using methods such as evaporation, distillation and electrolysis.
Finding and extracting mines
Finding mines is divided into two types of exploration and extraction. In the exploratory stage, the deposit is obtained by exploring various resources and working in circulation. In the extraction stage, the ore is obtained using different methods.
In the past, mining technology was done traditionally, but with the advancement of mining technology, there are more advanced methods for mining. Today, the use of various technologies such as all automatic machines, heavy machinery and other new technologies has made it easier to obtain minerals such as bitumen extraction.
Types of mines
Mines are divided into two categories, metallic and non-metallic.
Metal mines include minerals such as gold, silver, copper, bauxite, iron, nickel, zinc and platinum. Due to having suitable physical and chemical properties, these mines are used in various industries such as metal industries, automobile manufacturing, electronic industries, etc.
Non-metallic minerals include minerals such as gypsum, limestone, salt, marble, natural bitumen and gilsonite, sand, kaolin and barite. Due to having suitable physical and chemical properties, these materials are used in various industries such as construction industries, chemical industries, etc.
