Comparative study on the selective chalcopyrite

Chalcopyrite is a refractory ore, but in the presence of molybdenite its dissolution is sped up due to the formation of a galvanic couple. According to the electrochemical tests carried out, the decomposition potential for chalcopyrite and molybdenite is 730 mV and 925 mV, respectively.

How to carry on the flotation of Chalcopyrite Knowledge

The mixed flotation process first floatates chalcopyrite and other useful minerals in the ore, and then uses preferential flotation of copper to suppress other mineral processes and obtain qualified copper concentrate. This process is suitable for treating ore with low grade of raw ore and simple ore property.
