Silica is not separated from the sand. Companies mine “high purity and commercially viable deposits” that are processed “to increase the silica content by reducing impurities. [The sand]… is then dried and sized to produce the optimum particle size distribution for the intended application….”
The Industrial Minerals Association - North America (IMA-NA) represents companies which extract and process a group of raw materials known as industrial minerals: http://www.ima-na.org/ Many of these minerals are used to make glass. They may be able to help you find local sources for raw materials.

You may wish to try an internet search to find directories of suppliers. (For example: “industrial material suppliers Saudi Arabia”)
Take a look at Charles Bray’s Ceramic and Glass: a Basic Technology. Sheffield, UK: Society of Glass Technology, 2000. The pages include a list of some common raw (batch) materials used for glassmaking, as well as some representative glass recipes.
For a more in-depth discussion of raw materials used in glassmaking, try:
