About 5% of the earth's crust consists of iron ore. This stone contains veins of iron metal (Fe) in its heart, which makes up approximately 20% of each piece of iron ore. 98% of the iron ore mined around the world is used to produce steel. This not only increases the strength and resistance of the metal, but also can create an anti-rust, anti-wear and anti-corrosion alloy containing at least 50% of the element. Iron ore is one of the most important raw materials of the steel industry, and as one of the leading companies active in this field, Gari plays an important role in meeting the domestic and foreign needs of the country. In the following, you can learn how to extract iron ore and its application. /p>
Iron stone and its applications
Iron ore is one of the most common and widely used types of ore, which consists of more than 20% of iron, and after mining and processing, it is used as a raw material for steel production in Iran's steel factories. This stone is impure during extraction and due to its low grade, it is necessary to purify it. Therefore, it is processed and concentrated in several stages to increase the iron grade.
More than 98% of the world's iron ore is used to produce steel. Therefore, it is used in important industries such as automobile manufacturing, building construction, bridge and railway construction, home appliance manufacturing, etc. Among other applications that are considered for iron ore, we can mention coal washing, concrete and cement production, and pigment.
How to extract iron ore
Open cut system is usually used for iron extraction in Iran, which is not very complicated. Because iron ore deposits are not far from the surface of the earth and are usually several meters deep. However, the underground mining method can also be used. In general, iron ore extraction is carried out in the following four stages:
🔰Drill
In the first place, several holes are created in the ground using a drilling machine. The holes must be dug with a certain pattern and depth and filled with explosives. Thus, it is ready for the next step, the explosion.
🔰 Blasting
The blasting stage is carried out in order to crush rocks and gain access to iron ore reserves. Before the explosion, it is necessary to evacuate the environment and direct all employees to a safe place. The most common explosives used in ore mining are emulsions and mixtures of ammonium nitrate and gasoline.
🔰 Loading
To load the crushed stones in the previous step, it is necessary to use shovels and trucks. Shovels can pick up rocks from the ground and transfer them into the truck.
🔰 Shipping
After loading, the iron ore should be transferred to the factories and enter the processing stages. Dump trucks or trucks with a capacity of 100 tons are usually used for transportation.
