Carbonatite - an overview | ScienceDirect Topics

    H. O'Brien, in Mineral Deposits of Finland, 2015. Introduction. Carbonatite is a unique igneous rock type, in that it formed predominantly of carbonate minerals (of which it must contain >50 modal % by definition) along with lesser silicates, phosphate minerals, and oxides. The term carbonatite was introduced by Brøgger in 1921 in his studies of the Fen complex in Norway (Brøgger, 1921 ...

    The uses of calcite, in the form of limestone, for building stone and marble, for making lime and cement, for fluxing iron ore, etc. are well known. For these purposes, limestone is a cheap material, a dollar or two a ton. Pure calcite is ground to a fine powder, and is used instead of whiting. White calcite of good cleavage is used as stucco dash.

    10.11.2011 · Calcite. Calcite is a mineral, which contains calcium carbonate (CaCO 3). This is an abundant mineral on the earth surface. Calcite can form rocks, and they may grow up to large sizes. They are found in all three types of rocks, which are sedimentary, igneous and metamorphic rocks. Different varieties of calcites can be formed due to variations ...

    All members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong double refraction in transparent rhombohedron s. Calcite and Aragonite are polymorphous to each other. Although Calcite and Aragonite contain the same chemical composition, they differ in crystal structure.

    Calcite, crystallizing in the rhombohedral crystal system is the thermodynamically stable phase of calcium carbonate. Aragonite, calcite's orthorhombic polymorph, is about 1.5 times more soluble than calcite. Magnesian calcite is an important sub-group of carbonates that occurs as skeletal components and marine cements.

    Calcite Processing by Flotation for Beneficiation

    Calcite is activated and floated into the froth concentrate while the sericite, quartz, and other silicates are depressed and rejected into the flotation tailing. The froth from the last 2 or 3 cells of the "Sub-A" calcite flotation circuit may be recycled, if desired to maintain grade and provide a final refuse low in calcite.

    Calcite - Origin and occurrence | Britannica

    Calcite - Calcite - Origin and occurrence: A large percentage of the calcite in rocks was deposited in sedimentary environments; consequently, calcite is a constituent of several diverse sediments, sedimentary rocks, and their metamorphosed products. A minor amount of the Earth's calcite is of magmatic (i.e., igneous) origin; it is the chief constituent of the rare rock called carbonatite.

    Calcite is one of the most common and widespread minerals. It is a principal component of most sedimentary carbonate rocks (limestone, chalk, travertine, etc.) but occurs in metamorphic (marble, hydrothermal veins) and igneous rocks (carbonatite) also.The mineral is typically light-colored and large crystals have well-developed crystal faces.

    Calcite may replace phenocrysts in lava and crystal fragments in volcaniclastic rock, and they also replace all types of debris and matrix. Extensive replacement may make the former rock texture unidentifiable or form replaced carbonate rocks. Based on an analysis of the attitude of calcite, this type of replacement occurs subsequent to the chloritization and dissolution of feldspar. For ...
