In the area of Sayago, Zamora province, near the border with Portugal, there are few deposits of clays and kaolins produced by alteration of feldspar and mica transformed into kaolinite and subsequent partial modification of the kaolin in smectites.
The site was acquired by Euroarce in 2002. He immediately built a treatment plant through various processes of washing, separation, extrusion, drying and grinding enables us to obtain clay, kaolin, sand, bentonite and lenses for different uses and non-ceramic tiles.
The center of activity, clay products, are generally specialty materials with high alumina content and very white. Its main feature is that even low levels of use of ceramic materials provide a high green strength. This makes great demand by the leading manufacturers of high-end porcelain.
