Beneficiation of Lead-Zinc Ores – A Review: Mineral
2021.3.28 With continuous exploitation and expanding plant capacity, exhaustion of primary high-grade lead-zinc resources has already been initiated. 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.
