YvonJ. 7200997The aim of this study is to estimate, from the statistics (PCA), the variability of the clays from the deposit of Gounioube, in order to choose the different grades convenient for a given application and eventually correct the defective ones. Indeed, most of industrial minerals are used in fields where benefit is taken from variable properties that, directly or not, govern their applications. So, fourteen samples of kaolin clays from Gounioubé deposit (Ivory Coast), have been studied by chemical, crystallographic (X-Ray Diffraction (XRD)), spectroscopic (IR, UV, EPR), particle size and textural analysis.]]>Andji, Y.Y.J.,19981998Andji, Y.Y.J., J.
