In mineral processing operations, besides target minerals, slurries often contain various metal ions, including common ones with different valence states such as Pb2+, Cu2+, Fe2+, and Fe3+. These metal ions originate from multiple sources during the flotation process, including the dissolution of co-occurring metal minerals during crushing and grinding, the …
Lead-zinc ores typically contain a mixture of lead sulfides (mainly galena, PbS) and zinc sulfides (mainly sphalerite, ZnS), along with various gangue minerals such as quartz, calcite, and dolomite. The composition of these ores can vary significantly based on the geological formation, which affects the processing techniques used.
