Intergrown, sharp, cubic Fluorites that are zoned yellow, blue, and purple. The largest Fluorite is 4.4 cm, and the luster is good. Interspersed all around the Fluorites are small clusters of white scalenohedrons of Calcite, which are translucent to gemmy. The Calcites add a lot of visual interest to the piece, and the combination is unusual.

The beneficiation of fluorite ore is gravity separation and flotation process. The specificity of fluorite flotation: 1. Because industrial making hydrofluoric acid require calcium fluorite content>98% and silica <1%, fluorite flotation generally use 5-7 stages concentration; 2. When the PH of ore pulp is 8-11, the floatability is good. Another, increasing the temperature of ore pulp can ...

galena 7.4: barite 4.4: fluorite 3.2: calcite 2.7. If coal is being used instead, its relative density is about 1.3, in contrast to shale at about 2.5. When asked how they would separate the minerals in a large sample taken from a mineral vein, answers will range from dissolving it in acid (possible, but very expensive and environmentally
