Molibilidad del escombro diferenciado con posibilidad de incorporación al proceso Caron

Abstract

El suministro de escombro laterítico con contenido de níquel inferior y cercano a 0,9 % -llamado escombro diferenciado- constituye una variante tecnológica posible en el proceso Caron. El propósito de esta investigación fue determinar el comportamiento cinético de la molienda del escombro diferenciado, con posibilidad de incorporación al proceso Caron en Cuba, usando para ello las instalaciones del molino convencional de Bond del Centro de Investigaciones del Níquel. Se obtuvo que en la mena prevalecen los óxidos y oxi-hidróxidos de minerales de hierro y aluminio mezclados con serpentinas, con porcentajes de Ni de 0,845% y de Fe de 40,50% que permiten clasificarlo como escombro diferenciado. El análisis cinético del proceso de molienda del escombro mostró que las tasas de rotura específicas oscilaron en el intervalo de 0,89 min-1 a 0,20 min-1, correspondiendo los valores más altos a las fracciones de tamaño mayores. Los parámetros C y n del modelo cinético acumulativo resultan en 0,056738 y 0,384293, respectivamente, con un coeficiente de determinación superior al 88%.
