Silica Sand Price Trend and Forecast
About Silica Sand. Silica Sand contains at least 95% SiO2 and less than 0.6% iron oxide. The most common form of SiO2 is quartz, which is mined from hard rock deposits. It is chemically inert and is often white/colorless. However, the color of each sand deposit depends on the variety of minerals and rock detritus that make up the deposit.
