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 via froth flotation Figure 1 Chalcopyrite extracted from Zacatecas Mexico from Rob Lavinsky under a license
·Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method copper sulfide mineral particles are concentrated in froth and associated gangue minerals are separated as tailings However a significant amount of copper is lost into tailings during the processing; therefore tailings can be considered secondary resources or
