present, the first flotation step may be bypassed. Sometimes the final flotation stage is omitted, leaving a feldspar-silica mixture (often referred to as sandspar), which is usually used in glassmaking. From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture.

The flotation procedure and the reagents conditioning time were consistent with that in single micro-flotation experiments, and the appropriate amount of flotation reagents were added. Finally, the concentrate and tailing products were collected, oven-dried, weighted and assayed by chemical analysis for Li 2 O grade.

The flotation process of mixed mineral samples was the same as that for the single minerals, except that the weight ratio of apatite, potassium feldspar, and dolomite was 6:3:1. The grade of concentrate and tailings was obtained by multi-element analysis. The flotation test procedure is shown in Fig. 2.

Normally, flotation time was 1.5 to 2 minutes. Results and Discussion. The feldspar rougher concentrate grade, quartz tailing grade and recovery of feldspar were excellent in the non-HF tests. In general, tests on other ores indicated that recoveries obtained from the non-HF system were 2-3% lower than that obtained from the HF- system.

Flotation experiments performed on a quartz-feldspar mixture demonstrate that quartz can be floated selectively from feldspars in diluted solutions of hydrofluoric acid (HF) simply by the aid of a frother. High grades and good recoveries were obtained for both quartz and feldspars. A feldspar concentrate of 99.9% at a recovery of 95.6% was produced.
