Abstract The surface properties of enargite as a function of pH were investigated. The zeta potential values increased from − 10 mV (pH = 3) to − 45 mV (pH = 12) and no isoelectric point (iep) was detected. The zeta potential of enargite was highly sensitive to pH and interesting peaks/valleys, unusual in common sulfide minerals, were observed. In the present study, these results were interpreted on the basis of the chemistry of enargite, which is a tetra-thioasenate of Cu(I). A thermodynamic… CONTINUE READING
