Our minerals

The best of the earth
at your fingertips

We have 32 mining sites for the highest quality sepiolite, bentonite, attapulgite and phosphates, which represent over 120 million tonnes of raw material.
The acquisition of new deposits is one of our priorities, both for renewing our reserves and for offering each customer any other type of raw material that may meet their needs.

Tolsa Sustainability
Efficiency
and sustainable development
All our mining operations are respectful with the environment and are a source of wealth for the localities in which they are located. Most of the land we operate belongs to farmers, they are our partners in each project and their satisfaction is our commitment.
For us, the restoration of lands is key, and in areas that are especially desertified or arid, such as in Senegal, we lead annual reforestation campaigns.
Thanks to our mining activity we not only generate employment, we also supply energy and other basic services such as drinking water, transportation, health and education, to localities with difficulties.
Part of our commitment is reflected in our BSCI social certifications.
