Extracting a metal from its ore - chymistIn this experiment, copper will be extracted from malachite by reaction with sulfuric acid and then reduced from the acid solution using metallic iron. The reactions for these processes are. CuCO3 Cu(OH)2 + 2 H2SO4. → 2 CuSO4 + 3 H2O + CO2. Fe + CuSO4. → FeSO4 + Cu. Mineral. Composition. Copper. % by mass.Extracting Lead Materials from Ore - - NucleadLead is extracted from ores dug from under-ground mines. Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. Usually, lead is found in conjuction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable.
