We are Cavisa

More than 35 years promoting the Costa da Morte sustainable development

Caolines de Vimianzo - CAVISA, founded by Rio Tinto Minera Company and Xunta de Galicia Government, through the Sodiga, has strived since its inception to meet the task of recovering and supplying natural resources, industrial minerals necessary for the development of our society, facing the future with dedication, research and development of processes, products and markets.


The crisis in the paper sector of the 1990s requires us to modify the production model and the target markets by deciding at that time to focus more on the ceramic stilettos, queues, paintings. At the time it is studied to improve the recovery of caolins and other minerals, micas and sands.

In 1998 Caolines became part of the Veneta Mineraria SpA group, a strategic partner for global growth, particularly in the EU.

The 2000’s shows strong competition from the kaolin market with the entry of new Community partners into the European Union, while highlighting the significant reserves of Muscovite mica. A renewed vision, inspired by The Circular Economy and business symbiosis, and a comprehensive study of the needs and applications of today's markets, make Caolines continue its focused activity on the integral use of its deposits, supplying many sectors: paints, cosmetics, pharma, plastics, adhesives, automobile, composite materials, organic farming... and the new areas of environmental rehabilitation, construction or animal welfare.

Caolines de Vimianzo is a European Company of the 21st century integrated into the economic and social fabric of Costa da Morte, committed to sustainability, human and workers' rights, with the entrustment of carrying out its activity in an efficient and respectful way with the environment.
