Physical separation of iron ore: magnetic separation
A new technology of applying SLon-2500 magnetic separator to recover iron concentrate from abandoned tails. 2010. Semantic Scholar extracted view of "Physical separation of 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 an overview ScienceDirect Topics
3.11.2.5 Magnetic Separation. Magnetic separation is a process where a contaminant is first attached onto a magnetic carrier material (e.g., magnetite), and subsequently, the contaminant-laden carrier is separated under a magnetic field. The simplest magnetic separator is a permanent magnet.The application of coal-based reduction in the efficient recovery of iron from refractory iron-bearing resources is comprehensively reviewed. Currently, the development and beneficiation of refractory iron-bearing resources have attracted increasing attention. However, the effect of iron recovery by traditional beneficiation Review on coal-based reduction and magnetic separation for

Minerals Free Full-Text Separation Analysis of New Magnetic
To achieve the utilization of fine ilmenite (especially −0.075 mm) produced in the titanium-magnetite processing plant in Panzhihua, a radial turbulent outer-cylinder magnetic separator (RTOCMS), was developed in this study. After optimizing the conditions of rotation speed and water flow, an RTOCMS concentrate with TiO2 grade of 22.84% Dry magnetic separation is a technology that sorts magnetic minerals from gangue using air as the medium instead of water. When raw ore is fed to the magnetic separator, the magnetic particles are subjected to magnetic force due to the nonuniform magnetic field. When the magnetic force exceeds the competitive force (i.e., gravity and Dry Permanent Magnetic Separator Encyclopedia MDPI

Physiochemical separation of iron ore ScienceDirect
The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz (SiO 2). The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.High‑silicon iron ore tailings (IOTs) as mineral solid wastes derived from the processing and utilization of iron ore, which would threaten human health and the ecological environment if handled improperly. Coincidently, it consists of abundant quartz gangue. In this study, we proposed a superconducting high gradient magnetic Recovery and preparation of high-grade silica from iron ore
