calcite le tailing

  • Calcite

    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 variety of ...

  • Calcite Mineral | Physical

    Calcite is often the only mineral present, but in some sedimentary environments, calcite may be associated with dolomite, gypsum, anhydrite, chert, or halite. In hydrothermal veins, quartz and other common vein minerals such as pyrite, dolomite, fluorite, galena, and chalcopyrite may occur with calcite (Kauwenbergh, 2010) .

    The abandoned Kam Kotia Mine (Canada) is undergoing remediation. A geosynthetic-clay-liner (GCL) cover system was installed in the Northern Impounded Tailings (NIT) area in 2008 to isolate acid-generating tailings from water and oxygen and to mitigate sulfide oxidation. The cover system includes a vegetated uppermost soil layer underlain by a granular protective layer (sand), a clay moisture ...

     · Calcite precipitation is influenced by pH, because the urease enzyme will only be active at pH values specific for urea hydrolysis. Many investigators have reported that the optimum pH for urease is 8.0, above which the enzyme activity decreases (Stocks-Fischer et al. 1999 ; Gorospe et al. 2013 ).
