Fluorite (CaF 2 ), as an important strategic mineral source, is usually separated from calcite by the common froth flotation method, but this separation is still not selective enough. The development of a selective collector and/or depressant is the key to achieving high selective separation. 1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP or H 4 ...

Influence of Pulp pH on Flotation of Fluorite and Calcite ...

The optimum pulp pH of the flotation of fluorite and calcite is determined as 9.5~10 and 8~9 respectively. pH value should be controlled above 9 to depress calcite. Finally, 9.5~10 was determined as the optimum pH to float the fluorite from the calcium-containing fluorite ores.

Testing of New Collectors for Concentration of Fluorite by ...

To obtain acid grade fluorite it is necessary to use physic-chemical beneficiation methods such as froth flotation [7,8]. Froth flotation is based on surface reactions between minerals and chemical reagents such as collectors and depressant. These reagents are hydrophilic or hydrophobic allowing the separation of minerals in the pulp or froth phase.

Froth Flotation in Mineral Processing Minerallurgy

Froth floatation is a method of separation of minerals or particles, by taking advantage of the differences between their superficial proprieties in a water solution. It means forming a froth of particles bearing minerals, by a flotation action. Then recovered those particles selectively from the pulp. A

01-05-2013  At the given fluorite recovery, the flotation with the new scheme floated less calcite than that with the actual scheme. It indicated that the new scheme was more selective between fluorite and calcite in flotation, and thus was a better depressant for carbonate minerals (mainly as calcite), compared with the actual scheme.

Abstract: The effect of colloidal montmorillonite (MMT) on froth flotation of graphite, galena and fluorite was investigated in this work. The results showed that the presence of sufficient amount of colloidal MMT particles in the mineral slurry would be detrimental of flotation by reducing the recovery of minerals.

Advantages and Disadvantage of Froth Flotation Method

The froth flotation method is that the mineral selectively attaches to the air bubble by flotation reagent based on the physical and chemical properties of mineral surface. It is not difficult to see that the first two methods mainly rely on the nature of the ore itself, while the froth flotation method mainly relies on the added flotation reagents for separation based on the nature of the ore itself.

froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.
