About Us

We are the third largest boric acid producer in the world based in Chile in the Arica and Parinacota and Antofagasta regions.


Founded in 1986 with 100% Chilean investment capital, in Quiborax we work with state-of-the-art technology and high quality standards which allow us to reach more than 52 markets in an agile and safe way, through efficient ports strategically located in the Pacific Ocean.


We do Sustainable Mining. The protection of the environment, the development of the communities in which we are inserted and the safety, health and well-being of our collaborators are the pillars that guide us and that have forged our identity during more than three decades of history.

Values that inspire us

Safety of our operations, in order to ensure the physical and psychological integrity of our employees.

Respect for our workers, for current legislation, for the environment in which we operate and for the communities with which we work hand in hand.

Responsibility that is reflected in the decisions we make and the commitments we fulfill.

Closeness with our human teams, suppliers, clients and with the communities.

Quality present in all our processes and in the products that we export to the world.

Our operations are located in the macro mining area of northern Chile in the regions of Arica and Parinacota and Antofagasta. Thanks to a strict control of processes, technology and connectivity with the international ports of Arica, Antofagasta and Angamos (located on the Pacific Ocean coast) we are able to offer our products which we can send to any point on the planet.

Both our mines and our plants operate under strict security measures and meeting high standards of caring for the environment.
