11.27 Feldspar Processing - US EPA

A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process. The ore is crushed by primary and secondary crushers and ground by jaw crushers, cone crushers, and rod mills until it is reduced to less than 841 µm (20 mesh). Then the ore passes to a three-stage, acid ...

Flotation of quartz from quartz-feldspar mixtures by the ...

Nov 01, 2016  1. Introduction. Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O’Meara, 1939).Sandvik (1979) reported that HF creates a large difference in the minerals’ zeta potentials as the zeta ...

Feb 10, 2018  The flotation performance of spodumene and feldspar with four size ranges (0–19, 19–38, 38–45 and 45–75 μm) are investigated in single mineral micro-flotation tests. The results show that the maximum spodumene recovery is obtained with coarse particles of 38–45 μm, while for feldspar, the best flotation performance is found with ...
