The phosphorite in Logrosán are peribatholithic deposits. The outcropping granitic pluton called Sierra de San Cristóbal was formed about 350 million years ago and generated contact fluids that filled the tectonic faults of the massif with Proterozoic slates that make up the obliterated anticline of Logrosán. When it crystallized, five veins of phosphorite were formed in the vicinity of the granite stock.
The naturalist Willian Bowles cited phosphorite for the first time in Logrosán in the 18th century, and in 1779 the chemist Louis Proust published a work titled "The phosphoric stone of Extremadura". In the 19th century, with the rise of extensive agriculture, the demand for fertilizers skyrocketed, so English companies, inspired by Proust's article, moved to Logrosán and in 1863 mining work began. In 1907 the Pozo María was opened in the Costanaza Filón and during the 1920s it would become one of the main phosphate mines in Europe.
The highest quality mineral was transported to Salamanca and Villanueva de la Serena for transformation into fertilizers.
Next to the Costanaza Mine, a fertilizer factory was installed to transform material grade below 60%. Facilities were also built to obtain sulfuric acid that was used in the preparation of fertilizers.
After the Spanish Civil War, due to the lack of a railway route and the competition from North African phosphates, the Logrosán mines ceased to be profitable. Exploitation stopped in 1944 and its final closure came in 1946.
In 2009, the Logrosán Mines Museum was created and part of the galleries and facilities were rehabilitated for your visit.

La fosforita en Logrosán son yacimientos peribatolíticos. El plutón granítico aflorado denominado Sierra de San Cristóbal se formó hace unos 350 millones de años y generó fluidos de contacto que rellenaron las fallas tectónicas del macizo con pizarras proterozoicas que conforman el arrasado anticlinal de Logrosán, al cristalizar se formaron cinco filones de fosforita en las inmediaciones del stock granítico.
El naturalista Willian Bowles citó en el siglo XVIII la fosforita por primera vez en Logrosán y en 1779 el químico Louis Proust publico un trabajo titulado "La piedra fosfórica de Extremadura". En el siglo XIX, con el auge de una agricultura extensiva se dispara la demanda de abonos por lo que compañías inglesas, inspiradas en el artículo de Proust, se traladan a Logrosán y en 1863 comienzan los trabajos mineros. En 1907 en el Filón Costanaza se abre el Pozo María y durante los años 20 se convertiría en una de las principales minas de fosfatos en Europa.
El mineral de mayor calidad era transportado a Salamanca y Villanueva de la Serena para su transformación en abonos.
Junto a la Mina Costanaza se instaló una fábrica de abonos para transformar el material de ley inferior al 60%. También se ejecutaron instalaciones para la obtención de ácido sulfúrico que era utilizado en la elaboración de los abonos.
Tras la Guerra Civil española, ante la falta de un trazado ferroviario y la competencia de fosfatos norteafricanos las minas de Logrosán dejan de ser rentables. La explotación se detiene en 1944 y su cierre definitivo llega en 1946.
En el año 2009 se creó en Museo de Minas de Logrosán y se rehabilitó para su visita parte de las galerías e instalaciones.
