Abstract

<p>La presente invención se refiere a un método para procesar mena de laterita de níquel, que incluye los pasos de obtener una mena de laterita extraída de una operación minera 42; y alimentar la mena a un clasificador a granel 44 que comprende una disposición de sensor y un mecanismo de derivación que separa la mena en un flujo beneficiado de mena de laterita de níquel 28 en donde la ley de níquel es mas alta que la ley de la mena alimentada al clasificador a granel para su procesamiento adicional 52 por lixiviación o fundición de residuos 46. Esta configuración de mena de la mina, en una pila de almacenamiento de baja ley o residuos, y mezcla de manera eficiente la mena de alta ley selecionada para cumplir con las especificaciones del procesamiento posterior.</p><p> The present invention relates to a method for processing nickel laterite ore, which includes the steps of obtaining a laterite ore extracted from a mining operation 42; and feeding the ore to a bulk classifier 44 comprising a sensor arrangement and a bypass mechanism that separates the ore into a beneficiated stream of nickel laterite ore 28 where the nickel grade is higher than the nickel grade. ore fed to the bulk classifier for further processing 52 by leaching or smelting waste 46. This configuration of mine ore, in a low-grade or waste storage pile, and efficiently mixes the selected high-grade ore to meet post-processing specifications. </p>
