Calcite Wikipedia BME
Etymology [] Calcite is derived from the German Calcit, a term coined in the 19th century from the Latin word for lime, calx (genitive calcis) with the suffix ite used to name minerals It is thus etymologically related to chalk When applied by archaeologists and stone trade professionals, the term alabaster is used not just as in geology and mineralogy, where it is reserved for a 2009年7月1日 Furthermore, the energy requirements for grinding some materials, as for example, in the cement industry which requires the production of fines with surface area 3500 cm 2 /g, cannot be assessed Effect of grinding aids on the kinetics of fine grinding energy Calcite is a very common and widespread mineral that comes in a wide variety of forms and colors It is best recognized by its relatively low hardness (3) and its reaction with weak acids and rhombohedral cleavage It is fluorescent under UV light Highgrade optical calcite was used in World War II for gun sightsCalcite Mineralogy4Kids2022年1月1日 Calcite, in other words, calcium carbonate (CaCO 3), is a glassy shimmer, transparent, easily breakable, large crystal marble mineralIts Mohs hardness is 3 and specific gravity is in the range of 26–28 It is micronized by grinding then classification processes are applied, and offered to the user as natural ground or ground and coated calcite according to The effects on the grinding parameters of chemical, morphological
