Variables affecting froth flotation can be divided in two groups: chemical and physical. Reagents type and dosages take an important role depending on the ore type.
The next stage, i.e., the flotation of the mixed concentrates, has two options: a) regular flotation, where the fluorite is floated using fatty acid as the collector, while
The microflotation test showed that dextrin had obvious inhibitory effect on arsenopyrite flotation, but had no inhibitory effect on chalcopyrite flotation. After
The types and dosage of dispersant on the improvement of fluorite flotation were investigated; when the sodium polyacrylate (SPA) was used as the dispersant and

Fluorite (calcium fluoride—CaF2), also known as fluorspar, is an industrial mineral used in metallurgy, hydrofluoric acid production, and ceramics manufacturing. Based on the results from a previous study, a lowgrade fluorspar byproduct (20.0% CaF2) originating from the exploitation of a rare earth carbonatite deposit can be improved to
Variables affecting froth flotation can be divided in two groups: chemical and physical. Reagents type and dosages take an important role depending on the ore type. Flotation of fluorite ores typically used tannings to depress calcite and ferrous minerals, starch and/or dextrin to depress quartz and a fatty acid collector [8,[16], [17], [18]].
Fluorite is a nonrenewable mineral used to produce anhydrous hydrofluoric acid (AHF) and aluminum fluoride. The demand for lowgrade fluorite powder (CaF2 < 97%) has fallen sharply owing to the current market conditions. Therefore, a large number of fluorite concentrates have been improved by acid leaching. While this approach can
The microflotation test showed that dextrin had obvious inhibitory effect on arsenopyrite flotation, but had no inhibitory effect on chalcopyrite flotation. After treating the surface of arsenopyrite with dextrin, the infrared spectra showed that new characteristic peaks, indicating that chemical adsorption and significant interaction between
Different dispersants were added in the dispersion process to improve the efficiency of fluorite flotation. The types and dosage of dispersant on the improvement of fluorite flotation were investigated; when the sodium polyacrylate (SPA) was used as the dispersant and its addition is 0.5%, the concentrate grade of CaF 2 increased from 90% to 98%
Competition between the valuable and gangue mineral phases for the uptake of MP Dextrin is responsible for its observed decrease in efficiency in mixed mineral flotation. All three polymers were found to be reasonably selective in their action although at high dosages the polymers began to affect the flotation of the valuable minerals.

Fluorspar / Fluorite Mineral Flotation. Fluorspar (also referred to as fluorite) is a mineral composed of calcium fluoride, CaF 2. It is a naturally occurring mineral that tends to form in rocks that have been subjected to hydrothermal activity. These rocks can also contain metallic ores which may include sulfides of tin, silver, lead, zinc

Collector type and pulp pH play an important role in the lead–zinc ore flotation process. In the current study, the effect of pulp pH and the collector type parameters on the galena and
Increasing demand for lithiumion batteries has led to the development of several new lithium mineral projects around the globe. Some major mineral processing challenges these projects face are similarities in gangue and value mineral behaviour and poor selectivity in froth flotation. Unsaturated anionic fatty acids are the primary spodumene flotation

Pulp pH value plays a significant role in the froth flotation. Especially in the flotation of fluorite, the performance of flotation will be affected greatly by pulp pH. MO, a new kind of modified fatty acid was used as collector, and H2SO4 and Na2CO3 were used to regulate pulp pH in the experiment. The mechanism of influence of pulp pH on flotation of fluorite
