Abstract

Un proceso para reducir un material que contiene metales, el proceso comprendiendo: proveer un material que contiene metales (5), calentar el material que contiene metales por medios convectivos y/o conductivos y/o radiactivos (2), exponer el material que contiene metales a energía de microondas (MW, por sus siglas en inglés) (3), exponer al material que contiene metales a energía de radio frecuencia (RF) (4), y exponer al material que contiene metales a un agente reductor (8) El método, el cual no implica calentamiento dieléctrico guante la exposición a energía de MW y RF, permite mayor reducción química eficiente para la energía de los minerales naturales que contienen metales y concentra el mineral natural e incrementa el rendimiento de metalización.
