Our Kaolin range of products are mined from our own deposit that forms part of the well-known Grahamstown Kaolinite complex in the Eastern Cape province of South Africa.
Kaolin is a clay and belongs to the phyllosilicate group of minerals occurring as an aluminium silicate. Kaolin differs from other clays by having a low shrinking/swelling capacity and a low cation-exchange capacity. Our Kaolin’s can be supplied in bulk lump form straight from the mine or processed further by milling, drying and bagging at our Grahamstown factory.
Kaolin offers good wet and dry brightness, inertness and acid resistance, free-flowing fluidity in dry form, stable firing colour, excellent firing properties and is used in a wide range of industrial applications including ceramics (where low plasticity is required), soaps, paints & coatings, welding electrode manufacturing, agricultural process as a binder or slip-aid as well as a carrier and diluent in pesticides and herbicides when in dry form (>2% moisture content)
