At the low level of collector dosage, increasing pH from 9 to 11 enhanced copper separation efficiency from 81% to 86% for IPETC and from 77% to 86% for SIPX. Results of ANOVA showed that the maximum copper separation efficiency (%) was obtained at the dosages of g/t SIPX, 7 g/t IPETC and 20 g/t MIBC at pH 11.
