Froth flotation of fluorite: A review ScienceDirect
01/04/2021 Summary of fluorite flotation reagents. Combined with the existing data, the most commonly found fluorite flotation collector is the fatty acid, in particular sodium oleate. Still, the low-temperature resistance and low water solubility limit its application. The modified oleic and its derives via halogenation, sulfonation, sulfate, etc., can improve fluorite flotation. Besides, a single

4 Kinds of Fluorite Flotation Process
The flotation reagents for fluorite ore mainly use collectors and inhibitors. 1. Quartz-type fluorite beneficiation. Quartz-type fluorite ore is mainly composed of fluorite (with a content of up to about 85%) and quartz. There is only a small amount of calcite, barite, and sulfide. The key to its separation is mainly to reduce the silicon content of the concentrate. In order to separate quartz

Selective Flotation of Calcite from Fluorite: A Novel
Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available. In this study, a novel reagent schedule using citric acid

How to Improve Fluorite Flotation Beneficiation Effect?
Fluorite flotation reagents are mainly collectors, inhibitors, and pH adjusters. The collectors commonly used in fluorite flotation are mainly fatty acids. Under certain conditions, when the amount of fluorite flotation collector is large, the recovery rate is high, but the grade is low. Generally, the roughing operation will increase the number of collectors and maximize the recovery rate
