Based on the use of either dry or wet ore, magnetic separators are divided into dry iron or wet iron removal systems, respectively. Magnetic separators for sorting mineral dry allow the particles to move freely, otherwise magnetic separation can be degraded or severely affected to the point of separation not occurring.
Keywords: magnetic separator; permanent magnet; dry pre-sorting; iron ore; review 1.

The main commercial objects of magnetic separation are, first, the diminution of the amount of earthy gangue, with a consequent increase of the percentage of metallic iron in the product, and, second, the incidental elimination of phosphorus (usually present in apatite), and often of sulphur or titanium. A crude ore, carrying about 30 per …
Iron titaniferous sands, also called black sands, are a source of various magnetic minerals, such as iron and titanium (Fe–Ti) oxides, with countless scientific and industrial applications. Ecuador is deemed a geo-diverse country that contains deposits of black sands in the Andean and coastal regions; therefore, the industrialization of these …

Developments in the physical separation of iron ore. D. Xiong, ... R.J. Holmes, in Iron Ore, 2015 9.5.2 Utilization of subeconomic iron ores. As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only …
The first SLon-2500 vertical ring-pulsating high gradient magnetic separator was designed and built up in 2006. It was installed at the tails dam of Hai Nan Iron Mining Company to recover iron ...
This paper describes a study around the recovery of fine magnetite in the form of a pelletizing concentrate. The study is based on an evaluation of an iron ore by-product …
In another study, Ezhov and Shvaljov (2015) used a laboratory-scale EVS-10/5 magnetic separator for dry beneficiation of iron ore of the Backer deposit. This was done by analysing the influence of the current strength in the electromagnet winding of the magnetic separator on concentrate yield and recovery.
Electrostatic & Magnetic Separators. Table of Contents. The gradual depletion of high-grade mineral deposits and the necessity for development of lower-grade deposits, together with the increased demand for nonmetallic minerals, has increased the importance of the ore-dressing field during recent years. There is strong need for …
The industrial test results of this magnetic separator reveal that the iron grade improved by 9.3 percentage points and that the recovery rate reached 90.85% …
Several Indian workers have attempted microwave-assisted reduction roasting studies of low-grade Indian iron ores. In this regard, Rath et al. used microwave roasting followed by magnetic separation to achieve an iron ore concentrate of 63–64% Fe with more than 80% iron recovery from an iron grade of 57% Fe. In addition to the advantage …
of equipment is mainly suitable for kaolin and other non-metallic ore iron enhancement and wastewater treatment. In addition, this equipment is often widely used in the form of test equipment in ... high gradient magnetic separation, iron concentrate with iron grade of 42.61% and tailings with iron grade of 7.05% were obtained [7].
From Table 2, the iron elements were mainly found to exist in the form of magnetite, hematite, and limonite in the low-grade iron ore sample, and hematite and limonite occupied about 22.37 mass% of the total iron, which should be reduced to magnetite first.. The lignite, obtained from Xinjiang Province of China, was used as a …
However, problems arise when a part of non-magnetic, hexagonal pyrrhotite is present in ore samples or when dealing with pyrrhotite entrainments within magnetic ores, such as magnetite and iron-bearing sphalerite [14]. Therefore, flotation is commonly used instead of magnetic separation to achieve the separation of pyrrhotite [15].
