  • Gemstones in Mica Schist | Craig Turic

    Mica-schist is a rock composed essentially of quartz and mica, usually either muscovite or biotite. The mica is the prominent mineral, occurring in irregular leaves and in foliated masses. The mica plates all lie with their cleavage planes parallel to each other and give to the rock a striking laminated or "schistose" structure.

    Muscovite is the most common of the Mica Group minerals. It can be found in igneous, metamorphic and sedimentary rocks such as pegmatites, gneisses, schists and most common in granitic rocks where it is found in large crystals. These crystals are referred to as "books" since they can be split into paper-thin sheets. It is easily identified due to its smooth cleavage which

  • The recovery of sericite in flotation concentrates

    Sericite is a fine grained muscovite mica, which is widely distributed in nature. It commonly occurs in many base metal ores, where it can become a major diluent in the concentrates produced from these ores, as well as in igneous rocks. It can be strongly recovered in flotation froths under circumstances where it is both wanted and unwanted.
