Developing Effective Separation of Feldspar and

The zeta potentials of feldspar and quartz, untreated and pretreated by HF (2000 g/t) with DDA (5 × 10 −4 M) as a function of pH, are shown in Figure 4. The feldspar and quartz points of zero charge (PZC) are about pH 1.7 and 2.0, respectively . In general, the PZC of feldspar minerals are reported at pH 1.5–2.0, and quartz
