The most common sand is composed of particles of quartz and feldspar. Quartz sand particles are colorless or slightly pink, while feldspar sand has a pink or amber color. Black sands, such as those found in Hawaii, are composed of particles of obsidian formed by volcanic activity. Other black sands include materials such as magnetite and homblende.

Feldspar is found in igneous, metamorphic and sedimentary deposits in most countries (Bolger, 1995). Silica is often associated with the feldspars, occurring as quartz in pegmatitic deposits and silica sand in feldspathic sand deposits. The feldspars are conventionally separated from quartz using cationic long-chain
