However, it is also known as a \"green\" metal for the green patina that it acquires due to weathering. Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look. Beyond this, however, copper can truly be cited as the \"green\" metal both for its role in protecting the natural environment through its use in energy-saving applications 在 copper 上查看更多信息

    Copper extraction - Wikipedia

    Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant. Sulfide smelting
