— The chemical and physical properties of iron ore tailings are comprehensively examined in this review, and various beneficiation and metallurgical recovery techniques such as flotation, magnetic separation, leaching, …

Traditionally, iron ore is enriched by using either flotation or magnetic separation to selectively remove these contaminants (Flippov et al. 2014). Magnetic separation is used to enrich iron ore samples that demonstrate either para- or …

 — The SLon-1000 magnetic separator can treat weakly magnetic minerals in the size range of 0–2.0 mm, and has been used in industry for upgrading roasted kaolin of 0–0.2 mm particle size by removing the impurities comprising oxidized iron ore and other weakly magnetic minerals.

 — Using this device to sort raw ore with a magnetic iron content of 3% and particle size of < 3 mm can result in a good index of 11.40% concentrate grade, 0.7% tailing grade, and 80.29% recovery.

 — ABSTRACT: Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The hematite iron ore used in the investigation contains 53.17% …

 — Several techniques have been utilized to improve the quality of inferior iron ores, encompassing magnetic separation, gravity separation using hydrocyclones, spiral concentrators, and jigs, as well as flotation processes.

 — Magnetic separation technology utilizes magnetic differences between substances [13,14,15] and is widely used in the treatment of strong magnetic iron ore and the exclusion of ferromagnetic impurities from the mixture. In addition, it has large-scale application in the separation of fine-grained weakly magnetic iron and manganese ores, …

 — Removal of magnetic fine particles from carbon-black powder by utilizing the high gradient magnetic separation with a newly developed magnetic wire filter under dry condition was studied.

 — As the primary beneficiation method for iron ore, magnetic separation improves ore grade, reduces silica and harmful impurity content, and facilitates the smelting process [28], [32], [33]. Utilizing magnetic separation is an important step towards achieving green and low-carbon steel production.

In present study, magnetizing reduction of a low-grade iron ore has been carried out followed by magnetic separation of iron minerals to produce iron concentrate. A potential process has been developed for magnetizing reduction of hematite into magnetite with
