Magnesium Expert
Exploring the full potential of magnesia
Much more than magnesia experts, we are the guardians of this precious resource. In the service of limitless innovation, our scientific approach, our industrial mastery and our technical expertise are now recognized worldwide.
Research based on excellence
To develop truly innovative, reliable and high-performance solutions, in-depth knowledge of the raw material is crucial. For this reason, for more than 50 years, Terresis has been studying, experimenting and analysing the properties and reactions of magnesia.
Over time, we have become the benchmarks for this resource, always at the forefront of research to develop promising solutions and alternatives that respect our planet.
What sets us apart: passionate teams that collaborate with universities and scientific laboratories around the world, but also exceptional resources made available within the Groupe Roullier – from the analysis laboratory to the pilot plant integrated into the Centre Mondial de l’Innovation Roullier.
An unparalleled industrial mastery
Driven by the Groupe Roullier, the true embodiment of generations of industrial excellence, we make our integrated model an exceptional strength: located in Brasil and Spain, we have our own mines and industrial facilities. This allows us to protect what really matters and to continuously innovate – both in the field of solution research and in the search for industrial processes.
This total control over its value chain also gives Terresis great agility: thanks to the talent of our multidisciplinary employees and their in-depth knowledge, we adapt to the demands of our customers and the requirements of the markets. From extraction to calcination, through complex technical processes imposed by future uses, we transform ore into high-performance and innovative products.
An unprecedented technical expertise
We rely on exceptional human resources and cutting-edge technological tools: high-performance equipment, multidisciplinary teams of experts present in the four corners of the world, and increased knowledge of our customers’ concerns.
The result is new scientific advances in the field of animal and plant nutrition, but also in the field of industrial, refractory and environmental applications. These are manufacturing and formulation processes that are emerging and respond to environmental issues. These are high value-added solutions that renew the agricultural sectors and support industry players to face the challenges of tomorrow.
