This culminates into low grade, fine grain size, complex ore mineralogy, and poor liberation, thus, causing the beneficiation of lead-zinc ore a challenging task. This paper summarizes the classification of ore deposits and different beneficiation techniques that are currently employed for the treatment of lead-zinc ore.
