In any dry magnetic separator, the careful control of feed moisture is critical to avoid smaller particles sticking to larger particles (Oberteuffer ...
First, the magnetic properties of the ore were determined. Initially, the iron ore samples contained 34 wt. % Fe in addition to other gangue materials. Therefore, the ore was subjected to a hightemperature reduction roasting process between 800 °C and 1000 °C. Additionally, the magnetic separation process was also employed.
An artificial neural network model to predict the performance of induced roll highintensity magnetic separator while upgrading lowgrade iron ore fines is presented in the present investigation. Key process parameters of induced roll magnetic separator operation,, applied current, speed of rotor, splitter position, particle size, and feed rate, are used as the network input. A ...
Dry magnetic separator, as a key part of a prediscarding tailings process, can not only improve the iron grade of raw ore, reduce the costs of grinding, screening, separation and tailings dewatering, but also obtain coarsegrain dry tailings that can be sold directly, which dramatically reduces the cost of mineral processing (Ezhov and ...

Moreover, compared with the wet magnetic separation, dry magnetic separation offers an opportunity to exploit lowgrade iron ores in remote and arid regions that would otherwise be not considered ...
Magnetic separation technology plays an important role in upgrading such lowgrade iron ores, because the magnetic separation process possesses the combined advantages of large capacity and low operating cost, as well as being environmentally friendly.
dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re quires 500 to 1000 gal of water per ton of concen trate produced. This means extensive use of water resources, as well as disposal systems and some times complicated water reclamation systems. Some of the new low grade iron ore discoveries ...
1. Introduction. Ironcontaining ore beneficiation includes several stages. For example: crushing to −30 mm size class and rough magnetic separation, further crushing of the recovered magnetic product to −10 mm size class and final magnetic metal content upgrading. All operations use dry methods.
Magnetic separation has been applied in ore processing to separate magnetic materials, such as iron oxides, from the bulk of nonmagnetic minerals with smaller specific densities . This approach separates particles by passing finely ground ore particles through a magnetic field at different intensities.
The concentration of lowgrade magnetic iron ores, separating the magnetite crystals from the gangue by the use of magnets, is a field of work in which the lessons taught by the development of the porphyry coppers can be studied to advantage.
