Quartz Sand VS Silica Sand
The chemical composition of quartz is silicon dioxide (SiO2), and high-purity quartz sand means that the SiO2 content is higher than 99.9%. Quartz sand is a silicate raw material obtained through crushing and purification. To make high-purity and ultra-high-purity quartz raw materials, it is necessary to remove all impurities except silica.

Sustainable Process for the Extraction of Potassium from Feldspar …
To recover potassium from feldspar, a biowaste, i.e., eggshell, was used. The chief composition of eggshells is calcite. As it is a rich source of Ca, hence it is used with HCl to produce calcium chloride. Feldspar is an aluminosilicate mineral that bears potassium in the interstitial sites. To unlock the potassium from the interstitial sites, it was roasted with …
