Selective flotation of fluorite from calcite presents many problems because the two minerals have the same cation, Ca++, in their crystal lattices. ... Optimal fluorspar flotation was achieved ...

The physical and chemical properties of feldspar and quartz are highly similar, thus they cannot be easily separated effectively. In this work, the flotation separation of feldspar from quartz using sodium fluosilicate (Na 2 SiF 6; SF) as a selective depressant was investigated.Moreover, the influence mechanism of SF on the selective flotation …

It can be seen that the flotation selective index of scheelite changes with the addition of lead ions, the best selective index of 17 located between 1 ∼ 2 × 10 −4 mol/L lead ions. This result shows that the ratio of BHA: Pb 2+ keeps at 1 to 2 is the best condition for flotation of scheelite and depression of fluorite.

Optimal fluorspar flotation was achieved under the following conditions: 3.6 g/kg of sodium oleate as the collector, 2 g/kg of sodium silicate as the pH modifier and depressant, a conditioning ...

3.2. Flotation of Phosphate Ore Sparingly soluble minerals are hydrophilic. Selective hydrophobization of the desired mineral by various reagents is critical in determining the effectiveness of the separation process. The separation of sparingly soluble minerals from oxide and silicate minerals has been successfully carried out by flotation method.

Haematite can be beneficiated from the fluorspar tailings using reverse flotation. DDA is a more selective collector for silicon as compared to Betacol. 300g/t of DDA, 400-500g/t of starch and natural pH of 8 – 9 gave the best results of 60.8% Fe and 2.83%Si in the sinks.

fluorspar was investigated, and the overall performance of the column flotation was compared to theperformance of the existing conventionalflotation cells at theplant.

In this paper, the high selectivity of a novel depressant sodium polynaphthalene formaldehyde sulfonate (SPS) for the flotation separation of fluorite …

Large reserves of feldspar ore exist in the Aegean region of Turkey. The main colored impurities in these ores are iron- and titanium-bearing minerals such as anatase, rutile, sphene and ilmenite. In this study, a potassium feldspar ore containing mainly quartz and coloring impurities was subjected to beneficiation tests involving magnetic …

Flotation is the most efficient method to recover this type of fluorite. Fluorite and calcite contain Ca 2+. During flotation, the physical and chemical properties of the …

2.4 Fluorspar Flotation. Flotation of fluorspar must be extremely selective when producing acid grade concentrate. This selectivity is essential as the ratio of concentration is low, often up to 80% or more of the entire tonnage, and must be floated in the rough circuit.
