In a three-stage separation an overall yield of 66.5% wt can be achieved with a feldspar grade of 85% in the feldspar and 4.4% in the quartz. These results are mainly affected by modified straight electrodes that keep the fine feldspar out of the field once it reached the negative electrode.
Previously, a selective flotation separation of feldspar in the presence of HF was proposed by Fuerstenau et al. [] in an acidic environment (pH = 2.1).It was suggested that the HF method can achieve a good separation of feldspar and quartz with a high grade of feldspar and a high-quality quartz [].However, there is a large amount of chemical ...
As Fig. 14(a) shown, in the absence of Ca(II), the PPPDA could be adsorbed on spodumene, feldspar and quartz through electrostatic attraction or hydrogen bond between –NH 3 + group and the mineral surfaces. However, the amount of PPPDA adsorbed on feldspar or quartz was much more than that on spodumene.
