A Process Mineralogy Approach to the Flotation of Complex Lead–Zinc
Complex and non-sulfide lead–zinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a tool to …
