Separation of Kaolinite from Ion-Adsorption Rare Earth Tailings in .Jan 18, 2016 . Abstract. Several hundred million tons of ion-adsorption rare earth tailings exist in Ganzhou, Southern Chi- na, which is a severe environmental hazard. To reduce and reutilize the tailing, kaolinite has been separated from the tailings by mechanical separation in laboratory scale and pilot scale. The re-.separation the kaolin and stonesand,high extraction magnetic filtration of kaolin clay - The Clay Minerals .Abstrac~A new magnetic separation technique combines high magnetic fields, extreme gradients, and controlled retention time to separate feebly magnetic mineral contaminants from kaolin. Extraction of pyrite, siderite, hematite, iron stained anatase, and mica by magnetic filtration of kaolin significantly upgrades brightness.Kaolin, Bentonit, Kerastuk | Sedlecký kaolin a.s.: Plants and .Testing of material properties during crushing, grinding, washing, dry and wet screening, hydrocyclone classification; Electromagnetic separation of raw materials in dry .
