Each process has its advantages and disadvantages when separating limonite ore. Gravity separation offers a low-cost method but may need help recovering fine particles or efficiently removing impurities.Magnetic separation is highly selective but requires large equipment and may produce tailings with lower iron grades.Flotation has …
ABSTRACT. Comprehensive utilization of tailings resources not only solves environmental problems but also creates huge economic benefits. In this paper, fine weakly magnetic particles were extracted from iron ore beneficiation tailings and silica (SiO 2) was separated and purified using a superconducting high gradient magnetic …
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 …
In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than …

1. Introduction. The past decades have witnessed tremendous progress made in the magnetic separation technology that have significantly decreased the industrial grade of mined iron ore (Liu et al., 2020, Zeng et al., 2019).However, the extensive energy consumption and high capital costs required in utilization of low-grade …
This study aimed at the investigation of the effect of colloidal magnetic particles on the magnetic separation of iron ore tailings (IOT). For this, the synthesis and characterization of bare iron, iron-dextran, and iron-oleate magnetic particles is reported. FTIR spectra confirmed that the synthesized particles were composed by magnetite.
Our two-stage magnetic separator therefore combines a STEINERT MTP extracting magnetic drum with a STEINERT MSB traversing magnetic pulley. Whilst the former generates valuable scrap iron, the magnetic pulley in the second stage separates weakly magnetic components that represent impurities in downstream processes and can have …
