METALLURGY OF COPPER Metallurgy of copper means EXTRACTION OF COPPER,POWERPOINTPRESENTATION ON METALLURGY OF COPPER.,from molten matteSulfuric Acid Leaching of Smelter Matte,Sulfuric acid leaching of lead smelter mattes resulted in the recovery of about 45 pct of the nickel and cobalt and 10 to 45 pct of the copper. The addition of manganese dioxide increased the cobalt and nickel recovery from 45 pct to greater than 90 pct, and increased the copper from 10 to 45 pct to nearly 100 pct recovery.Synchronous extractions of nickel, copper, and,The extraction of Ni increases from 40.19% at 300 °C to 93.18% at 500 °C, and then it decreases rapidly with the increase of roasting temperature. The extractions of Cu and Co increase from 32.18% and 33.89% at 300 °C to 90.01% and 87.54% at 450 °C, and then they decrease rapidly with increasing roasting temperature.
