Assessment of die Industrial Potential of Major Porter Clay Deposit in Plateau State, Nigeria. Science Forum Journal. Pure and Applied Vol. 4(1). ATILPress.https://keffi.nsuk.edu.ng/handle/20.500.14448/5668articlePhysical and chemical properties of Major Porter and Nahuta deposits of Barkin Ladi area of Plateau State, Nigeria were investigated. A total of eight (8) samples (Four from each deposit) were collected, processed and analyzed using standard analytical technique. Physical properties like colour, texture, swelling capacities and luster were examined right from the field while others like clay content, plastic limit, liquid limit, were examined in the laboratory. The chemical composition was determined using XRF. Comparison of both physical and chemical properties of the two deposits with industrial specifications reveal that the two kaolin deposits are not suitable for industrial use in their natural state and so will require some forms of benefaction which will range from screening/filtering and blending before it can be used in some of the industries.enKaolin; major porter; nahuta; benejiciationArticle
