Fluorite

S.K. Haldar, in Introduction to Mineralogy and Petrology (Second Edition), 2020 11.3.12 Fluorite. The fluorite or fluorspar is a halide mineral (Figs. 1.15 and 1.16 Figure 1.15 Figure 1.16) and composed of calcium fluoride (CaF 2).The fluorite often occurs as veins with metallic minerals. The fluorite is the principal source of fluorine and used as flux in open-hearth steel furnace.

9 Ore Deposits and Economic Minerals – Mineralogy

The best metal ore minerals are those that contain large amounts of metals of value. Most metallic ore minerals are native elements, sulfides, sulfosalts, oxides, or hydroxides. Ore deposits are highly variable in nature and origin. The most important kinds of ore deposits are …

The effect of fluorine on liquidus phase relationships in ...

Liquidus phase relationships have been determined experimentally for the system Qz-Ab-Or with excess water and 1, 2, and 4 wt.% added fluorine at 1 kb pressure. With increasing fluorine content the position of the quartz-alkali feldspar field boundary moves away from the quartz apex. The position of the minimum melting composition and the minimum liquidus temperature change progressively from ...
