- How To Separate Silica Sand From Raw Sand
The primary difference between silica sand and regular sand is the steel content. Silica sand is made up of quartz crystals, which are hard and have a high degree of crystalline silica, while regular sand is made up of fractured rocks, coral, shells and other organic material that tends to have a more diverse make-up.
