extraction of copper oxide in portugal

Copper Mining and Extraction Oxide Ores,Most of the copper ores mined today are oxide or sulfide ores Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction Sulfide Ores 11–14 but is introduced here because an important byproduct of this process is used for the extraction of oxide ores Pyroprocessing Sulfide Ores Provides Acid for Leaching...

    Why is the extraction of copper from pyrites more

    In the Ellinggam diagram graph of Δ r Go vs T for the formation of oxides copper copper oxide line is almost at the top Hence oxide ores of copper can be easily reduced to copper by heating with coke The Δ Go vs T lines for CO show negative slope at high temperature Hence it can easily reduce copper oxide to copper However Δ Gf for sulphide ores are higher than that for CS2
