Is muscovite mica felsic?

Common felsic minerals include quartz, muscovite mica, and the orthoclase feldspars. The most common felsic rock is granite, which represents the purified end product of the earth's internal differentiation process.

How do you dissolve muscovite?

In general, the muscovite is dissolved and separated from quartz sand by coupling the effects of calcination and fluorine-free acid leaching.

Will muriatic acid eat gold?

Gold will not dissolve ia muriatic acid alone, although it will be attacked by chlorine. ... The most useful and important vehicle for dissolving gold is aqua regia, (royal water), composed of two parts of hydrochloric (muriatic) acid, and one part of nitric (aquafortis).

Does mafic or felsic cool faster?

Felsic magmas tend to be cooler than mafic magmas when crystallization begins (because they don't have to be as hot to remain liquid), and so they may start out crystallizing pyroxene (not olivine) and plagioclase.

What kind of mica is found in Muscovite?

Muscovite (hydrated aluminium potassium silicate [KAl2 (AlSi3O10) (F, OH)2 ])and phlogopite (potassium magnesium aluminum silicate hydroxide) are the two major micas of commerce. Micas are commonly found in ordinary rocks. Inhalation of mica dust presents an occupational hazard. DryPowder; PelletsLargeCrystals

Which is mica is most resistant to chemical attack?

Micas are generally resistant to chemical attack with the exception of muscovite (which decomposes in hydrofluoric acid) and phlogopite (which is mildly attacked by hydrochloric acid and decomposes in hot sulfuric acid) Gerhartz, W. (exec ed.).

What kind of alkali is used to dissolve mica?

Mica, like all silicates, is slowly dissolved by hot concentrated alkali. Gold will survive this procedure, but many other metals don't.
