  • The Extraction of Copper - Chemistry LibreTexts

    Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation). Figure 1: Chalcopyrite extracted from Zacatecas, Mexico.
