What did they mine in Santa Rosalia?
They have arrived in Santa Rosalía, an old mining town where a French company created not only one of the world’s major copper-producing mines, but a company town with a decidedly French flavor. It all started in 1868 when copper ore was discovered by rancher Jose Villavicencio.

It is also known to be an aid for the treatment of the liver, kidneys, and skin. Brookite it particularly useful for use after surgery, owing to its highly beneficial and effective healing properties that can aid the process of recovery.
How is brucite formed?
Brucite (Mg(OH)2) has an hexagonal structure (space group Pm1). It is often formed from the alteration of periclase (MgO) in Mg-bearing limestones and dolomites. These occurrences can be due to low-temperature hydrothermal alteration or metamorphism of limestones and schists and during the serpentinization of dunite.
