Conclusion. In this study, a methodology for separating quartz was developed and tested on sediment and rock samples from the Himalaya. Method was able to extract pure quartz (95-96%) from the sediment and rock samples. SEM image analysis shows that proposed method was able to bring down feldspar content to ~ 4-5%.

A superhydrophobic-oleophilic quartz sand with WCA of 154.0 ± 1.2° and SA of 4° was developed by using the superhydrophobic nano-silica particles to treat quartz sand [21]. The obtained quartz sand presented good ability of oil-water separation. However, the preparation of superhydrophobic silica nanoparticles is a bit complicated.
