An innovative precise low-intensity magnetic separator (PLIMS) was developed for recovering low-grade magnetite. The effects of the key parameters on the separation performance of the PLIMS in recovering magnetite were investigated. The results indicated that the drum rotation speed and feed particle size played major roles …

A wet low-intensity magnetic separator (LIMS) is the workhorse for winning magnetite from a slurry. However, the issue with optimizing LIMS is the balance between attracting too much material and obtaining mixed grains of extremely low-grade material (less than 20 vol% magnetite) in the concentrates and attracting too little material and …

Low-intensity magnetic separation tailings (LIMS tailings) are a common by-product obtained after magnetite magnetic separation. In this article, various techniques such as chemical analysis, X-ray diffraction, ICP-MS, and Mineral Liberation Analysis (MLA) were employed to investigate the LIMS tailings. The primary iron-bearing mineral ...

Various classification schemes of magnetic separators have been introduced and probably the most practical and logical is the one that classifies separators as either dry or wet. At the same time, these separators can operate with a low-intensity or high-intensity magnetic field (Svoboda, 1987). This scheme does not take into …
