Predictions of triboelectrostatic separation of minerals in …
XRD patterns and XRF results of three minerals are shown in Fig. 3 and Table 1 respectively. The XRD pattern of kaolinite Fig. 3 (a) is in good agreement with the standard kaolinite 1A phase (chemical formula Al 2 Si 2 O 5 (OH) 5, PDF79-1570) and the XRD pattern of quartz Fig. 3 (c) also fits quite well with the standard quartz (chemical …
