Whether your needs involve crushing, grinding, gravity separation, or dewatering, we have the equipment and technology you require. Partner with us to make iron ore beneficiation simpler and more reliable. Feel free to contact us to learn how to optimize your beneficiation process.

The seemingly simple process of iron ore beneficiation is, in fact, a progressive one. Beneficiation techniques in the market are generally divided into two categories: gravity separation and flotation.

Gravity separation methods are commonly used for the beneficiation of coarse and medium-grained iron ores. These technologies rely on the differences in density between valuable minerals and gangue materials. Jigging machines, shaking tables, and spiral chutes are commonly used for gravity separation. They effectively separate heavy minerals, facilitating the concentration and recovery of iron ore particles.

Flotation is a widely used technique in the beneficiation of iron ores, particularly suitable for fine-grained ores. This process relies on the chemical and physical properties of the ore, involving the selective attachment of air bubbles to valuable minerals. Flotation cells, collectors, and frothers are used to separate and concentrate the desired minerals while suppressing unwanted gangue materials. To enhance flotation efficiency, beneficiation plants should select suitable reagent regimes, dosage methods, and flotation systems.

If you have any further questions or need assistance with your iron ore beneficiation process, please don’t hesitate to contact us.

iron ore beneficiation process

Crushing and screening: To separate the fine ore from the bigger rocks and waste, the mined iron ore is first crushed into small pieces.

Grinding and classification: Using grinding mills, the crushed ore is then processed into a fine powder. Then, based on the particle size distribution, this powdered ore is divided into different sizes.

The larger iron ore particles are separated from the lighter gangue minerals using gravity separation processes. Shaking tables, centrifugal separators, and spiral concentrators are common pieces of gravity separation machinery.

Utilizing magnetic separation, contaminants and magnetic materials are taken out of the iron ore concentrate. In this step, magnetic separators like drum magnets and high-intensity magnetic separators are used.

Flotation: When silica and other impurities are present in substantial amounts in iron ore, flotation is used to selectively remove them from the iron ore concentrate. For this, froth flotation is frequently employed.

Dewatering: After beneficiation, the iron ore concentrate could still have some moisture in it. To lower the moisture level and get the concentrate ready for shipping, dewatering procedures including filtering and drying are performed.

Storage and Delivery: Before being sent to steel mills or other clients for additional processing, the finished iron ore concentrate is kept in bins or stockpiles.

Jaw crusher

Jaw crusher Working principle: jaw crusher (jaw crusher), with a large crushing ratio, uniform product particle size, simple structure, reliable work, easy maintenance, economic operating costs and other characteristics.Jaw crusher commonly used electrical equipment: soft starter low-voltage electrical appliances (contactors, circuit breakers, etc.)

 

Cone crusher

The hammer crusher is one of the main equipment for fine limestone, coal or other brittle materials below medium hardness in metallurgy, building materials, chemical industry and hydropower and other industrial sectors, with a large crushing ratio, high production capacity, uniform product particle size and so on.
Hydraulic cone crusher commonly used electrical equipment: soft starter low-voltage electrical appliances (contactors, circuit breakers, etc.) electromagnetic coupler hydraulic coupler

Ball mill

Working principle of the ball mill: The material is uniformly entered into the first bin of the mill by the feeding device through the feeding hollow shaft. There is a stepped lining plate or corrugated lining plate in the bin, which is loaded with steel balls of different specifications. The centrifugal force generated by the conveying of the cylinder will bring the steel ball to a certain height and then fall down, which will have a pounding and grinding effect on the material.
