Wastewater Treatment and Reuse. Y. Gong, D. Zhao, in Comprehensive Water Quality and Purification, 2014 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 …
Dry permanent magnetic separators have been widely used in the mineral and coal processing industries due to their simple operation and high separation efficiency. These tools not only discard some amount of bulk gangue from the raw ore, thereby reducing the volume of the grinding operation and cutting energy consumption, but also do not require water in the sorting …

Magnetite was easily oxidized to weakly magnetic hematite, which was unfavorable for magnetic separation. Besides, the ΔG θ of Eq. (6) was higher than 0 when the temperature was below 600 °C, suggesting that the pseudobrookite was unstable and easily decomposed into hematite and rutile at low temperatures.
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.
Magnetic Separation. After the sample is dried, it is ready for magnetic separation. The magnetic separation process is necessary in order to rid the sample of any metals already within the original sample. Furthermore, metals also react and destroy the heavy liquids by producing a precipitate that is difficult to filter. Procedure
Magnetic separation has been recognized as a valuable technique for extracting or separating target materials from mixed heterogeneous particles. In conventional geological research, it has been used to separate ferro- and ferri-magnetic minerals such as Fe–Ni metal, magnetite and ilmenite. Recently, a mixture of diamagnetic and weak paramagnetic particles …
