Silica sand is a mineral resource. It is mined mostly for glass-making. Another major use of sand is a concrete production but that does not need sand to be as pure. Some beautiful beaches are made of silica sand. Beach of Siesta Key in Florida is especially famous for its white sand. Not all white sands are made of silica, though.

Selenite, also known as satin spar, desert rose, or gypsum flower are four crystal structure varieties of the mineral gypsum.These four varieties of gypsum may be grouped together and called selenite.

Sodium selenite usually is prepared by the reaction of selenium dioxide with sodium hydroxide: SeO 2 + 2 NaOH → Na 2 SeO 3 + H 2 O. The hydrate converts to the anhydrous salt upon heating to 40 °C. Akin to the related salt sodium sulfite, Na 2 SeO 3 features a pyramidal dianion SeO 3 2−. Oxidation of this anion gives sodium selenate, Na 2 ...
