Clay is a mineral formed from the weathering and transportation by water of parent rocks which are deposited in ancient river basins from where it is now extracted.
Our Cyferfontein clays are lumpy clays with alumina contents varying from 19 to 22%.
Used either as a binder for refractory brick production, or as additives to improve plastic behavior during installation.

Clay is essential for ceramic production because of its high plasticity, strength and deflocculation properties.
Clay is used as a binder for the formulation of kiln furniture parts.
Kaolin clays are noted for their fine particle size, large exchange surface and low hardness. These are valuable natural properties for the formulation of glues, elastomers, masterbatches and PVC.
