Magnetic Separation SpringerLink
In the case of fine, feebly magnetic minerals, the best choice for magnetic separation is high-gradient magnetic separators . Dry low-intensity magnetic separators (DLIMS) are generally employed to: upgrade iron ores containing relatively large particles and strongly magnetic minerals. separate iron pieces from steel mill slags and blast The optimum grade that could be obtained from single-stage dry magnetic separation was 35.52% Mn, and with a Mn:Fe ratio of 1.77, and 44% Mn recovery in the case of sample 1; whereas, a 33.75% Mn grade, with a Mn:Fe ratio of 1.66 at Mn recovery of 44% was reported for Sample 2. It was observed that both samples had a similar input chemistryDRY MAGNETIC SEPARATION OF MAGNETITE ORES ScienceGate

Influence of process parameters of dry high intensity magnetic
However, the low-grade iron ores are attendant with unwanted gangue minerals such as silica, alumina, clays, apatite, and calcite. Standard physicochemical methods such as froth flotation and gravity separation (spiral concentrator, jigging, heavy media separation) were used to separate the gangue minerals from hematite are Four different iron minerals were selected for study, and five size fractions of each mineral were prepared. The magnetic properties of these minerals were measured. The effect of particle sizeWet High Intensity Magnetic Separation of Iron Minerals

Separation and Recovery of Iron from Low-Grade Refractory Iron Ore
The low-grade iron ore fines contain weakly magnetic iron minerals such as hematite and siderite, which could not be separated effectively by low-intensity magnetic separation. Therefore, the ore fines were magnetized by magnetization roasting, then low-intensity magnetic separation was used to enrich magnetic iron minerals.Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic substances. The process that is used for magnetic separation separates non-magnetic substances from those which are magnetic. This technique is useful for the select few minerals which are ferromagnetic (iron-, nickel-, and cobalt Magnetic separation

Magnetic Separation and Iron Ore Beneficiation IspatGuru
Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.Dry medium-intensity magnetic separator (DMIMS) plays a vital role in enhancing the separation of low-grade raw magnetite ore. A good understanding of the dynamic separation process of DMIMS would further boost its economic competitiveness in minerals processing and engineering. Herein, this study analyzed the basic structure and Dynamic behavior and separation prediction of magnetic ore
