• Fluorite

    Fluorite or fluorspar is the mineral form of calcium fluoride (CaF 2).The mineral may occur as massive (Fig. 1.15) or vein-type deposit, in association with metallic minerals forming a part of mineralization.The associated minerals include barite, calcite, quartz, galena, sphalerite, and pyrite (Fig. 1.16).The vein-type mineralization is of hydrothermal origin.Fluorspar / Fluorite Mineral Flotation - ArrMazIt is a naturally occurring mineral that tends to form in rocks that have been subjected to hydrothermal activity. These rocks can also contain metallic ores which may include sulfides of tin, silver, lead, zinc, copper and other metals. Fluorspar / fluorite mineral can also be found in some limestone and dolomite deposits.
