Minerbloq company, has had more than half a century of experience since we started in 1954 the working of the salt spring "Marķa Luisa" mine, located at "El Salinar" spot, in La Villa de Calasanz (Huesca).
Later on , we developed not only our own production but also the marketing of every single kind of salts , marine salts as well as gems. In the nineties, we started the manufacture of mineral blocks for livestock, becoming one of the main producers not only in a national level, but also in an European framework, with important exports to the European Union and other different countries.
