Se estudia el comportamiento reológico de un mineral procedente de las minas de Djebel Ghassoul (Marruecos Oriental) encontrando que sus propiedades coloidales son superiores a las otras muestras de interés industrial presentando poco efecto frente a sustancias salinas y sus propiedades dispersantes se acentúan con la adición de pequeñas cantidades de hexametafosfato sódico. El mineral tiene un importante contenido en flúor y se comporta como material adecuado para pasta dentrífica así como para la fabricación de jabones a los que proporciona una baja alcalinidad.
Rheological properties of a sample from Djebel Ghassoul mines (Eastern Morocco) is studied. The colloidal properties are superior than those of similar industrial earths. such as; low sensivity to coagulation by salts and high dispersing power, which can be enhanced by the addition of small cuan ti ti es of other dispersing agents such as Na-hexametaphosphate. It can be advantageously used for the manufacturing of soaps. to which it imports a low degree of alcalynity and also of tooth pastes. due to its high fluorine contents.
