Flotation is one of the best methods of concentration in various industries. In other words, flotation is the same flotation that increases the grade of iron ore in the production of iron ore concentrate. On the other hand, it can be said that today this very good and widely used method is widely used in the iron ore mines of the country. Because they can increase the grade of iron ore using this method.
Flotation is considered the best method of separating minerals from minerals and soil due to its wide range of applications. It is also used to process minerals in various fields. As we know, in the past, low-grade minerals and ores were abundant and there was no way to increase their grade. But today, manufacturers and experts have tried to increase the grade of low-grade minerals by using a highly practical method called flotation.

The importance of the flotation method
Flotation has many advantages and benefits. One of its best and most important advantages, as we have stated, is the separation of minerals from soil minerals. In other words, minerals in mineral soils are separated by flotation and are used in various industries. Although this method is used to separate minerals, it is also used in various industries to perform other activities, including industrial wastewater treatment, paper recycling, mineral sulfur removal, etc. To learn more about this method of increasing iron content in the production of iron ore concentrate, we will explain its advantages and applications below. We will also learn more about this method of mineral separation. (Increasing the strength of steel by sintering)
Iron enrichment by flotation:
Flotation and its cells are used in various mines around the world. It can also be said that due to the spread and abundance of flotation, from the twentieth century onwards this method was recognized as one of the best and most suitable methods of increasing the concentration of iron ore and rocks in the production of iron concentrate. The method of increasing the concentration of iron in the production of concentrate is a bit difficult and complicated and consists of various parameters. Therefore, each of the parameters in this method affects the performance of each other and is dependent on each other. Therefore, their examination and evaluation cannot be done alone.
Parameters in flotation
The parameters in flotation are divided into three categories:
.Initial parameters: These parameters are related to feed and manpower
.Chemical parameters: Chemical parameters include chemical characteristics, environmental conditions of the process, etc
.Mechanical parameters: Mechanical parameters are related to the design and type of flotation machine, the layout of the circuits, their types, etc
In the method of increasing iron grade to produce concentrate, minerals are first separated from mineral soils. Then they are crushed into different sizes and shapes so that they can be easily mixed with water. For this purpose, minerals that are exposed to water are mixed with water. Then they are suspended on the water and wet. But let us also say that not all minerals have this ability.
In the continuation of the flotation process, chemicals are used. Because these materials make the flotation activity and performance optional. Also, the extractors can separate and adjust valuable and worthless minerals from each other. In this method, from the beginning of the process to the last moment, they use stirring devices to prevent the settling of materials and solid phases. Because stirring and mixing the pulps prevents the settling of these materials. It also increases the grade of minerals and minerals.
Important principles in the flotation method
The flotation method is based on the chemical and physical properties and characteristics as well as the desired environmental conditions. In other words, this method is based on creating the appropriate air flow in the desired environment. One of the most important principles in this method is crushing the minerals after they have been discovered and separated. For example, after the minerals have been discovered and crushed to a specific size and dimensions, the miners pour the resulting materials into preparation tanks. Also, at this stage, chemicals are added to the preparation tanks.
After the minerals and minerals escape with water, they are introduced into various flotation devices and equipment. Flotation is carried out in two ways. Direct and indirect flotation. After the minerals are introduced into the flotation devices, the direct and indirect flotation processes are carried out. That is, in the direct flotation process, valuable minerals and minerals are separated. On the other hand, in the indirect flotation process, worthless and waste minerals and minerals are separated from valuable minerals and float as a flotation foam. After completing all the steps and processes we have mentioned, the minerals and minerals, including iron ore, are concentrated to produce iron concentrate and their grade increases.
Flotation circuits
In terms of flotation, it should be said that in iron processing and enrichment plants, various flotation circuits are used to produce iron concentrate. The use of these types of circuits requires precise industrial, semi-industrial, and laboratory calculations. One of the most important goals of using flotation circuits in the enrichment of minerals and iron ore is to produce quality and acceptable materials. Since different circuits are used in this method of increasing iron content, each of them has its own advantages and applications. For example, simple circuits produce only one type of product. But other circuits are capable of producing several very high-quality products.
In addition, if we want to examine the applications and benefits of flotation, we can say that this method is one of the most widely used methods of increasing the grade and concentration. This method is also used to process base materials and metals. Various iron ore mines in Iran also benefit greatly from this method.
:Other advantages of this widely used method include the following
Increase in minerals and minerals that have fine particles
Enriching iron ores to produce very high recovery concentrates
Ability to crush particles and increase the grade of low-grade minerals
This method is applicable and used for all types of iron ores and minerals
Ability to separate different minerals from each other with the same physical properties
