In this study, methods for reducing iron (Fe³⁺/Fe²⁺) compounds in Angren kaolin were studied. The initial sample contained 1.32% Fe₂O₃. As a result of magnetic separation, acidic and thermal-chemical treatment, the Fe₂O₃ content was reduced to 0.12%, and the degree of bleaching of kaolin exceeded 80%. The obtained purified kaolin was found to be a promising raw material for the production of zeolites, adsorbents and ceramic products.
