The lead–zinc ore is a typical low-grade complex polymetallic sulphide ore. Its typical mineralogy is characterized by a high content of cryptocrystalline graphite, low content of lead, zinc, and copper, and fine grain size. However, the aggregation size of sulfide mineral aggregations is coarse, and the symbiotic relationship is relatively simple. …

Lead ore is primarily composed of lead sulfide (PbS), which is the most common mineral form of lead. Other minerals that may be present in lead ore deposits include cerussite (lead carbonate, PbCO3), anglesite (lead sulfate, PbSO4), galenite (lead sulfide, PbS), and other lead-bearing minerals. The concentration of lead in lead ore …

Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
