Determinación experimental de la distribución de níquel entre macrofases de mineral laterítico cubano
Abstract
Se seleccionaron 8 muestras de ocres inestructurales provenientes de diferentes yacimientos cubanos, cuyos contenidos de hierro oscilan entre 37-51 % y los de níquel entre 1,0 y 1,62 % Se trataron consecutivamente con 3 disolventes selectivos en el siguiente orden: NHa - NHCl , (NHt,)2 H Cit, HCl concentrado. Se aplicó el esquema de análisis químico de fases elaborado para minerales lateríticos cubanos, con el objetivo de determinar la cantidad de níquel asociado a las dos fases principales: goethita y serpentina. El contenido de níquel, no unido estructuralmente, osciló entre 0,3-1,4 % con respecto al contenido total del elemento; el contenido asociado a los silicatos (serpentina) entre 6,5-22,8 % , y el níquel asociado a la goethita y las espinales entre 73,5-96,3 %.Downloads
