  • kaolin. British Geological Survey

    2. GEOLOGICAL OCCURRENCE. Kaolin deposits are generally classified as either primary (residual) or secondary (sedimentary). The mode of formation of the kaolin may have considerable influence on the mineralogy, chemistry and morphology of the clay and may dictate the type of mining and beneficiation process.
