Abstract
Se proporciona un proceso para la producción de ferroníquel a partir de la laterita incluye como mínimo una proporción de material relativamente fino con un tamano inferior a 10 mm. El material de alimentación también puede estar compuesto por completo sustancialmente por finos o polvo de laterita, y puede reducirse previamente, opcionalmente después de secarse. La laterita se introduce en la zona central de bano en fusión de un horno circular, en el que como mínimo un electrodo situado en la bóveda actúa como cátodo, y el propio bano en fusión como ánodo El proceso puede utilizarse para tratar de forma económica mineral fino de laterita previamente desechado y acumulado, e incluso yacimientos de laterita anteriormente no viables..
