Enhanced recovery of low-grade copper ore and associated …
Zhang et al. [23] studied the process mineralogy of copper ores and found that copper minerals are mainly sulfide minerals that are easily floated, but most of them are embedded at around 0.3 mm, requiring a grinding fineness of 85–90 % −300 mesh to make the copper ore fully dissociated. The study of process mineralogy holds a significant ...
