Processes magnetite hematite limonite iron ores.
Magnetite uses weak magnetic separation methods.
Hematite uses gravity magnetic flotation routes.
Limonite uses roasting magnetic separation flow.
Siderite processing depends on ore grade traits.

The iron ore beneficiation process improves iron concentrate recovery through crushing, screening, grinding, classification, gravity separation, magnetic separation, flotation, reverse flotation, and combined beneficiation flows.
Different beneficiation routes can be selected according to iron ore type, mineral composition, iron grade, magnetic properties, particle size, and liberation characteristics.
The production line can be configured with automatic feeding, crushing, screening, grinding, classification, magnetic separation, flotation, gravity separation, concentrate collection, and tailings discharge systems.
The process can be customized for magnetite, hematite, limonite, siderite, mixed iron ore, low-grade iron ore, and polymetallic associated iron ore.
Magnetite, hematite, limonite, siderite, or mixed iron ore enters the beneficiation plant.
The beneficiation route is selected according to iron ore type, mineral composition, grade, and magnetic properties.
Raw iron ore is crushed to reduce particle size before grinding and separation.
Crushed ore is screened to control suitable feed size for the next processing stage.
Magnetic pulley separation can remove surrounding rock before grinding for simple magnetite ore.
Iron ore is ground to achieve suitable liberation between iron minerals and gangue minerals.
Ground slurry is classified, and coarse particles return for further grinding when required.
Strongly magnetic magnetite is recovered through weak magnetic separation.
Silica and other gangue impurities are removed when magnetite concentrate grade needs improvement.
Weakly magnetic iron minerals such as hematite, limonite, and siderite are recovered under strong magnetic field.
Spiral chute, jigging, or shaking table separation is used for coarse or medium-fine hematite, limonite, or siderite ore.
Positive flotation or reverse flotation improves iron concentrate grade according to ore properties.
Weak magnetic, strong magnetic, gravity separation, flotation, or roasting methods are combined for complex mixed iron ore.
Rough concentrate is cleaned to improve iron grade and reduce non-metallic impurities.
Qualified iron concentrate is collected for steelmaking and metallurgical applications.

Optimized magnetic separation, gravity separation, flotation, and combined beneficiation flows help improve iron mineral recovery from different ore types.
Proper ore-type-based process selection helps reduce unnecessary grinding, reagent consumption, and energy use.
The process can be designed for magnetite, hematite, limonite, and siderite beneficiation.
Magnetite ore can contain about 85% iron-bearing magnetite minerals, making weak magnetic separation highly suitable.
