Ankerite structure is basically composed of calcium carbonate as well as different amounts of iron, magnesium and manganese. Ankerite mostly fluorescence, is a secondary ore, limestone and dolomite formed under the action of the magnesium solution. Facet body ankerite crystal morphology was similar to the dolomite, but also that the massive and coarse granular.
The ankerite typically is pale yellow, and can also colorless, white, gray, and beige. The main producers are Namibia, South Africa, Austria, Japan, Canada, western United States, and so produced this ore. Benin cement clinker grinders
The ankerite use is used to extract calcium carbonate, the raw materials used in chemical, concrete, cement and other raw materials. Ankerite and dolomite is not easily distinguished, ankerite containing divalent iron exists in the surface weathering will turn brown limonite generated shell, often associated with chlorite, siderite, calcite, dolomite symbiosis and other minerals.

Dolomite minerals in cold dilute hydrochloric acid reaction, but quickly dissolved in hot dilute hydrochloric acid. In marine sediments, sometimes because the oxidation reduction conditions change, free iron ion out of the formation of ankerite carbonate and calcium.
In the marine environment can be used as redox indicator minerals. In addition, Hungary Bauxite crusher the Precambrian iron in the sedimentary layer of iron carbonate is ankerite. The ankerite often among the carbonate-type deposits or hydrothermal vein-type deposits.
