Restauración y primeras oleadas revolucionarias (1815-1830)

En 1815 los vencedores de Napoleón se reúnen para poner fin a la página histórica iniciada en 1789 con el estallido de la Revolución Francesa. Sin embargo, la Restauración entendida como intento de restablecer el Antiguo Régimen, choca con la dinámica de transformación histórica representada por la Revolución. Por eso, la reacción sólo se mostrará en Eruopa de forma parcial y provisional. En 1820 y 1830 se producen sentas oleadas revolucionarias que ponen de manifiesto las crecientes fisuras del sistema de la Restauración. en 1848 una generalizada, aunque momentánea, primavera de los pueblos, largamente incubada, constituirá la decisiva crisis del proyecto de reacción simbolizado en el Congreso de Viena. Por debajo de esta pugna entre reacción y revolución, Europa desarrolla, con la generalización de la Revolución Industrial en el continente, una activa vida económica. La sociedad y la cultura europeas constituen un hervidero de intereses, proyectos y actividades que conforman el complejo panorama histórico de la primera mitad del siglo XIX.

This chapter is related with the preliminary study of some non-metallic minerals to evaluate their cationic exchange capacity, to remove heavy and precious metals, as well as rare earths elements. The minerals and materials used to execute the ion metals removal were bentonite, phosphorite, and diatomite. The chapter shows the physicochemical behavior of all these minerals, which were used to remove the mentioned elements from solutions coming from ore leaching. It was found that in all cases, the removal of heavy and precious metals, as well as rare earths elements reached over 90%. Although, there were minimal differences in efficiency for all minerals used (bentonite, phosphorite, and diatomite), it could be pointed that the phosphorite has the best results going from 99.43% of removal of Gd, to 99.95,Äì100% for the case of Ce, Nd, La, Yb, Eu, Er, Sm, Tb, Ge, Pd, Pt, and Au.
