While traditional magnetic separation technology can remove strong magnetic minerals like magnetite, it proves ineffective against weakly magnetic iron-bearing minerals such as hematite and limonite. This limitation makes it difficult to meet the high-purity requirements of advanced ceramics and premium coatings demanding raw materials with exceptional whiteness and low iron content. Against this backdrop, superconducting PTMS MAGNETIC SEPARATOR magnetic separation technology has emerged as a groundbreaking advancement in deep iron removal for kaolin processing.
Superconducting PTMS MAGNETIC SEPARATOR utilizes low-temperature superconducting coils cooled in liquid helium or nitrogen to generate stable strong magnetic fields exceeding 5 Tesla, far surpassing the magnetic field strength of conventional electromagnetic or permanent magnet devices (typically 1-2 Tesla). This ultra-strong magnetic field effectively captures weakly magnetic particles at the micron and even sub-micron scale, significantly enhancing the selective separation capability for paramagnetic minerals such as hematite (Fe₂O₃) and siderite (FeOOH).
A kaolin mining area in south China was formed in a weathering residual sedimentary environment. The raw ore has a high Fe₂O₃ content of 2.3%, and is mainly deposited in the form of fine-grained dispersed limonite and hematite between or on the kaolinite layer. The removal rate of traditional dry magnetic separation is less than 40%, and superconducting PTMS MAGNETIC SEPARATOR can be used for iron removal process.
