Description
Summary:Kaolin is an important industrial mineral which is used by many process industries including paper, paint, plastics, ceramics, rubber, and many others. Several standard tests must be performed to fully evaluate the economic potential of kaolin. These include mineralogical determinations by X-ray diffraction, scanning electron microscopy, differential thermal analysis, and the petrographic microscope; particle size distribution; grit percentage (material larger than 44 microns); color (brightness and whiteness); viscosity; resistivity; particle shape; beneflciation response (chemical leaching, flotation, high intensity magnetic separation); ceramic tests (green, dry, and fired strength, shrinkage, fired color, porosity, fusion temperature); and surface area. Other tests that are used include oil absorption, gloss, opacity, abrasion, moisture, pH, reagent demand, and others.
