THE ACTIVATION OF SULFIDE MINERALS FOR FLOTATION - A REVIEW

The chemistry of the activation of sulphide minerals by Cu(II) and oth er cations is reviewed, with special emphasis on work published in the past two decades. An attempt is made to resolve anomalies in the publ ished results and theories, and to suggest directions which further wo rk should take so as to advance understanding of the processes and to improve performance in the selective flotation of sulphide ores.
