2020-1-1 The performance of chalcopyrite flotation was used as the final factor in determining the characteristics of both the grinding media. The results indicate that the Fe 3+ concentration and the pH of the pulp obtained by grinding with CB medium were lower, while the dissolved oxygen content was obviously higher, than those of the pulp obtained by grinding with CIB medium.

Breakage Characterization of Grinding Media Based
It is generally accepted that grinding is a random process in which the degree of grinding depends on the probability of the mineral entering into the region between the grinding media particles (the “probability of contact”), and the probability of breakage of the mineral after contact with the grinding media (the “probability of breakage”) [2,3]. Generally, the contact probability is related to the specific surface area of the grinding media

Bureau of Mines research showed that galvanic interactions between grinding media and chalcopyrite influence the self-induced floatability of chalcopyrite in simulated process water. Similar results were obtained with a synthetic chalcopyrite-quartz mixture and a natural ore, and floatability was dependent on the electrochemical conditions in grinding, conditioning, and flotation stages.
