Dry high-intensity magnetic separators are one of the most common magnetic separation methods extensively used for the concentration of paramagnetic minerals based on their magnetic susceptibility, particle size, particle density, and shape.
The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes. The aim of the research is to study the …
Herein, the importance of physical separation methods of ores in mineral processing is widely acknowledged. Of interest is the magnetic separation, gravity concentration and sensor-based separation…
Dry separation methods can basically be broken down into three main types of mechanical separation procedures: air classification, screening and specific-gravity separation. The chemical process industries (CPI) have many applications that require classifying or separating solid materials. Examples of separation or classification processes ...
Furthermore, physical separation techniques, commonly used in mineral processing and offering a remarkable potential for sulfur and valuable minerals enrichment, are rarely used to manage mine wastes.
As mineral deposits are becoming increasingly more finely disseminated, and water scarcity has become a global issue, investigation of dry separation in fine sizes is of great importance.
This separation can be done either physically, via gravity separation, electrostatic separation, and magnetic separation, or chemically, using froth flotation, leaching, and electrowinning. Unusable minerals, which are often discarded into dams, are called tailing. In order to understand the benefits of dry mineral processing, you must first ...
Spirals, the most common equipment for the separation of heavy minerals such as chromite, are greatly affected by size distribution and the liberation degree (hence the specific gravity and size) of the feed particles. In this study, the efficiency of spirals in separation of low-grade chromite particles has been investigated by studying the …
Magnetic separations take advantages of natural magnetic properties between minerals in feed. The separation is between economic ore constituents, noneconomic contaminants and gangue. Magnetite and ilmenite can be separated from its nonmagnetic RFM of host rock as valuable product or as contaminants. The technique is widely used in …
A gravity concentrator namely "vibrating table" has been developed with the objective of increasing the product quality of density based physical separation processes. The system is mainly composed of a vibration unit, an inclined chute, TW and WW jets. The principle idea of the separation is to combine the involved forces of a …
Physical separation includes gravity concentration, classification techniques such as hydrocyclones and air classifiers, solid–liquid separation (e.g., thickeners and clarifiers), magnetic separation, and electronic sorting. This Special Issue will discuss the latest findings of using physical separation in mineral processing.

Gravity separation is a method in which materials/minerals are separated based upon the difference in particles density [1]. Water as a medium is an important factor in improving the differential movement between various particles during gravity separation and eventually sorting different particles [2]. When water is removed, and air plays the role of …
This dry separation technology is also successfully employed in mineral processing [ 7, 8, 9, 10] and the food industry [ 11, 12 ]. As a perfectly dry method, electrostatic separation is an environmentally friendly technique that has received special attention due to the increasing scarcity of water resources.
Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases.
Magnetic separation is an important technique in mineral processing and has many applications in various industries. So, what exactly is magnetic separation and where is it used?
An economic comparison of using the tribo-electrostatic belt separation versus conventional flotation for barite / quartz separation illustrates the advantages of dry processing for minerals.
The modular structural design allows fine-grained minerals with different magnetic susceptibility to be separated in one pass, according to their different processing …
High intensity dry magnetic separators are gaining popularity for the separation of para-magnetic minerals due to the cost economic factor.
These cause an increase in the process energy cost, which is the most important challenge that the mining and mineral processing industry is currently facing. Undoubtedly employing innovative separation technologies would make processing procedures more efficient, sustainable, and cost-effective.
To enhance dry magnetic separation of fine-grained materials, our research team developed the pneumatic drum magnetic separator (PDMS), an airflow-aided magnetic separator. Different positions at the separation surface of PDMS have varied separation angles, so particles at different positions may be subjected to varying …
Dry separators based on terminal velocities follow single step for dry beneficiation of mineral, and air velocity in this type of dry density separators is maintained between terminal velocity of high density and low density particles. Iron ore is considered as feed material to illustrate separation behavior in both separators.
Many ores are not readily amenable to concentration by gravity, flotation, or other conventional methods. For example, the dry separation of minerals having a small specific gravity difference is an extremely difficult problem. Therefore, the Bureau of Mines has conducted research to develop new treatment procedures and to develop new types …
Both ferromagnetic (low intensity) and paramagnetic (high intensity) separation devices ( Laboratory Magnetic Separator) may be operated with dry solids or with solids in pulp form. (A complete classification of magnetic separating devices is given in Wills "Mineral Processing Technology", pp. 338-356).
