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 ...

Enhancing flotation separation effect of fluorite and ...

For fluorite, the flotation recovery increased from 84.1% to 91.4% throughout the pH range studied. Meanwhile, the recovery of fluorite and calcite can reach 91.18% and 93.84% respectively at pH 9.0, which indicated that the effective separation of the two minerals cannot be realized only by adjusting pulp pH.

Fluorite flotation process - Yantai Jinpeng Mining ...

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 ...

success in the flotation of fluorite. These collectors include, fatty acids, oleic acid, sodium oleate, and various soaps. Depressants are also a vital part of successfully treating fluorite. Commonly used depressants include, quebracho for calcite and lignin sulfonate and sodium fluoride.for barite and ...

4 Kinds of Fluorite Flotation Process

Flotation is the main method of fluorite beneficiation, and the development of high-efficiency flotation reagents and improvement of the flotation process are the keys to improving flotation indexes. The core issue of the fluorite flotation process is how to effectively sort and separate fluorite ore and associated ore (commonly quartz, calcite ...

Froth flotation of fluorite: A review - ScienceDirect

It prohibits fluorite flotation at pH = 6, and thus benefits the reverse flotation. Fluorite can be activated at pH = 8, and then enriched by flotation. Thus, pH is the key parameter controlling the efficient separation. However, the cost of organic phosphonic acid is relatively high, limiting its application in industry.

The invention discloses a collector for the floatation of fluorite at a low temperature. The collector comprises the following raw materials in weight portion: 35 to 45 portions of fatty alcohol polyethenoxy ether carboxylic acid sodium, 40 to 50 portions of sodium cetanesulfonate, and 8 to 12 portions of fatty acid methyl ester sodium sulfonate.

Flotation of fluorite from ores by using acidized water ...

1. Introduction. Fluorite flotation is usually realized with sodium lignosulfonate as depressant and fatty acid as collector at a high pH (Crozier, 1992, Ayhan et al., 2006).In the case where feed ores contain a significant amount of fine particles, the sedimentation rate of fine particles was found to be significantly slow due to the effective dispersion of the fine particles when ...
