Chemical properties of MicaFort

Phlogopite Mica is a hydrated silicate of potassium and magnesium whereas Muscovite Mica a hydrated silicate of potassium and aluminium is.

MicaFort origin

Muscovite is a constituent of acid igneous rocks like granite, pegmatite or alaskite, some regionally metamorphosed rocks and clastic sedimentary rocks, ad is a product of alteration. Most commercial deposits are derived from pegmatites which contain 1-2% and rarely up to 10% muscovite. Mica is found in many regions of the world in the form of pegmatite rock and mica schist.

Phlogopite is associated with metamorphosed limestone and ultrabasic rocks, particularly hydrothermal veins formed through metasomatism of magnesium-rich rocks as well as ultrabasic and carbonatite ring intrusions associated with ancient shield areas. LKAB Minerals’ Phlogopite Mica is sourced from a major deposit in Finland.
