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 ...

Micro-flotation experiments demonstrate that Ca 2+ and Mg 2+ can selectively recover lepidolite but not feldspar when the pH is above 6.5 during alkali etching. The activation of Cu 2+ and Fe 3+ flotation is not selective and can activate lepidolite and feldspar to some extent, irrespective of alkali etching. Through the …

Our flotation cell, which has a volume of 600 cm 3, is built of borosilicate glass, holds up to 90 g of sample, and achieves quartz and feldspar separation in ≤2 h for very feldspar-rich samples. We trace the stepwise enrichment of quartz to 95– purity with our procedure by X-ray diffraction analysis.
