Abstract

Se proporciona un proceso de separacion de minerales que permite hacer una separacion eficiente entre el mineral de cobre y el mineral de molibdeno. El proceso de separacion de minerales comprende una etapa de acondicionamiento para adicionar un sulfito como agente de tratamiento superficial a un lodo mineral que contiene un mineral de cobre y un mineral de molibdeno, y una etapa de flotacion para realizar la flotacion utilizando el lodo mineral despues de la etapa de acondicionamiento. Aumentando la hidrofilicidad del mineral de cobre selectivamente con un sulfito, se puede dar una diferencia entre la hidrofilicidad del mineral de cobre y la hidrofilicidad del mineral de molibdeno. Por consiguiente, se puede hacer flotar e l mineral de molibdeno selectivamente, permitiendo asi hacer separacion entre el mineral de cobre y el mineral de molibdeno eficientemente.
