A study of the colloidal and chemical properties of hydrodispersed clay from the Southern region of the Republic of Kazakhstan revealed variations in sediment volume, optical density, and filtration process depending on the clay sample's type, origin, and settling time. These differences were attributed to factors such as chemical composition, particle size, and the interaction between solid-phase particles and the dispersing medium. Additionally, the study comprehensively examined various characteristics of the clay samples, including zeta potential, colloidicity, electrical conductivity, salt content, and pH.
