Copper-Lead-Zinc ores Danafloat

Generally the lead mineral, typically galena, readily floats and optimum collector selection for copper will provide good lead recoveries. In some cases, maximizing bulk copper recovery may require use of thiocarbamate and thionocarbamate collectors in conjunction with dithiophosphate and xanthate chemistries in bulk flotation.

Lead ore and mines Minerals and mines Foundations of

Lead ore and mines Mineralisation. The lead, zinc and copper veins on Mendip were deposited by hot mineralising fluids (typically between 50 and 150° C) rising up from depth and depositing various minerals as they cooled. The source of the fluids were the deep sedimentary basins either side of the Mendips.

Copper in the Roman Empire UNRV

To smelt "sulfide" minerals, (that is minerals made of copper, iron, lead and zinc chemically bound to sulfur), it has to be heated and "oxidized" first. The more easily smelted ores were exhausted by the time of the fall of Rome. The Moors lived in southern Spain during the Middle Ages. They used copper for cooking utensils and for ornaments.
