feldspar and quartz

 · 01 Alkaline flotation process Quartz and feldspar are separated in the alkaline pulp with a pH value of 11-12. The quartz is preferred to surface by reverse flotation with alkali earth metal ions as active agent and alkyl sulfonate as a collector, and the appropriate non-ionic surfactants are added, which obviously improve the quartz recovery rate.

Dust Control Measures in the Construction Industry | Annals of …

 · The percentage of quartz was calculated from the mass of quartz and the total gravimetrically determined respirable dust on the filter. Samples with quartz levels below 1.7 µg ( n = 4) were set at two-thirds of this value divided by the average sampling volume, which resulted in a limit of detection for quartz measurements of 1.6 µg/m 3 .
