Feldspar flotation as a quartz-purification method in ...

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.
