The research examines how three raw clay materials consisting of ABS, PS and NUR22 receive mineralogical and chemical treatment for beneficiation before ceramic suitability evaluation. The naturally occurring fine-grained materials hydrous aluminum silicates which are the main constituents of clays show industrial ceramic potential because they exhibit plasticity alongside thermal stability and sintering behavior. The color and surface quality of fired products suffer when iron oxides exist in ceramic materials because they impede high-quality ceramic applications. The research aimed to decrease the Fe₂O₃ concentration for industrial ceramic applications because it improves both whiteness and functional properties of the clays. The initial research involved granulometric separation followed by X-ray fluorescence (XRF) and X-ray diffraction (XRD) analysis to study the chemical makeup and mineral structure in different particle sizes.
