According to different physical and chemical properties of the ore, using the gravity method, flotation method, and magnetic separation method to separate useful minerals from crushed gangue minerals and decrease harmful impurities in the beneficiation process.
Mineral resources can be divided into metal, the non-metal and combustible organic mineral from the perspective of the industry. Except for purity iron ore with little percentage, most of the minerals need to be processed before they can be used because some iron ores are kind of low grade. While the main method of processing is beneficiation.
There are many beneficiation plants for different ores, such as phosphate rock beneficiation plant, silica sand beneficiation plant, bolivia lead ore beneficiation plant, barite beneficiation plant, and tantalite beneficiation plant. And in general, there are two ways to implement the process of mineral beneficiation and ore dressing, one is by gravity and the other is floation.
The gravity method is to separate minerals based on the difference in relative density of minerals. Mineral particles with different densities influenced by fluid power and various mechanical forces, which will result in suitable loose delamination and separation conditions to separate the different density of the ore particles.
Non-ferrous metal ores such as copper, lead, zinc, sulfur, and molybdenum can use the flotation method to process. Some ferrous metals, rare metals and some non-metallic ores, such as graphite ore, apatite, etc.are also selected by flotation.
The magnetic separation method is based on the difference of mineral magnetism, and different minerals are subjected to different forces in the magnetic field of the magnetic separator. Non-ferrous and rare metal ores such as iron, manganese, and chromium can use the magnetic separation method to separate from the minerals.
For the three methods, they have the same necessary machines in the beneficiation process, such as feeder, PE jaw crusher, PEX jaw crusher, ball mill, spiral classifier, and all these machines can be supplied from FTM Machinery. Generally, water is usually used to clean minerals during the beneficiation process.
In addition to the necessary equipment, different beneficiation methods also have a certain machine. The gravity beneficiation line also use the jigger, spiral chute, shaking table; flotation beneficiation line uses the stirring tank, flotation cell, foam tank, and dryer; magnetic beneficiation line uses the magnetic separator or dryer. Generally, water is usually used to clean minerals during the beneficiation process, but there is a kind of iron ore mining that does not require water. Correspondingly, its purity is low.
The magnetic separation line consists of feeder, jaw crusher, screen, ball mill, classifier, magnetic separator, concentrator, and dryer. They combine with hoist and conveyor to make up the complete beneficiation production line.
This beneficiation production line has the advantages of high efficiency, energy-saving, large capacity, and economy. Customers usually process the ore in the beneficiation plant. The following three basic processes are generally included.
1.Preparation. Before the beneficiation, we should crush, screen, grind, and classify the raw ore. The purpose of this process is to separate the useful minerals from the gangue mineral monomers and to dissociate the various useful minerals from each other.
Besides, this process creates suitable conditions for the next separation process. However, some beneficiation plants dont wash or select waste ores because of ore properties and the need for sorting.
2.Separation. Fote company uses the methods of gravity, separation, and flotation to separate useful minerals from crushed gangue minerals and let the useful minerals be separated from each other. Finally, you can get the concentrates, tailings, and sometimes mines.
In the process of beneficiation, the first step is called rougher. The crude product obtained by rough selection is further selected to obtain final products with high quality. The next step is called the cleaner. And the last step is a scavenger. The crude product after roughly selecting is further selected, and the middle ore is returned to the first step or processed separately to get high recovery products.
1.Compact structure. Fote company offers the necessary equipment of the beneficiation process to customers. The advantages of close cooperation between the equipment, high-speed material circulation can help customers save plenty of time.
4.Energy-saving and environmental. The beneficiation production line is equipped with perfect dust removal equipment. The reasonable layout is beneficial to convey the raw materials. And the sprinkler system can reduce dust during the production. Moreover, noise pollution is small.
If you have any project about the mining, FTM Machinery can provide you the equipment you want. Besides, we have the complete after-sales service system, so you dont be worry about the installment or technical support problems.
