Reducing quartz entrainment in fine coal flotation by

Jan 01, 2019· To better understand the flotation performance, coal and quartz were separated from the froth product. Fig. 4 presents the recoveries of coal and quartz as a function of PAC concentrations. As can be seen in Fig. 4(A), when SHMP was not added, the quartz recovery was 37.40% in the absence of PAC and it steadily reduced to 26.78% as PAC concentration increased to 50 mg/L.
