Mitigating the negative effects of feldspar slime on
The micro-flotation tests showed that the negative effect of feldspar slime on spodumene flotation could be reduced by using the mixed NaOL/DDA collector with mole ratio of 9/1. The scanning electron microscopic images and the adsorption test results indicated that the decrease of spodumene recovery was attributed to collector consumption by feldspar slime.

2015-9-10 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
