anionic collector alone. Also, fluorite flotation could be improved by using effective depressants when fatty acid is used as collector. For example, acidized sodium silicate was reported to depress calcite strongly in preference of fluorite at ambient temperature, leading the fluorite flotation to be achieved at a lower temperature [4].

Fluorspar flotation froth has a tendency to build up on the thickener surface, but this can be taken care of by retaining rings near the overflow lip and by sprays so only clear water overflows the thickener. Thickened concentrates at 50 to 60% solids is removed by a Adjustable Stroke Diaphragm Pump, feeding by gravity to the filter.
