· Copper sulfide ore has good inherent floatability so flotation process is a mature method used for copper sulfide ore separation. In recent years with the continuous development of copper sulphide flotation technology many scholars also proposed a series of new principles of mineral processing such as "collect early loss early" and "more crushing and less grinding".
