Heating flotation (Petrov's method) refers to the process of thickening and dewatering the rough concentrate (solid accounts for 60 % −70 %) obtained from roughing at room temperature, then vigorously stirring with a large amount of sodium silicate at high temperature (90–95 °C), and finally cleaning after diluting, also called heating ...

Fluorspar, also known as fluorite, is commonly used as a raw material to produce fluorinated chemicals (e.g., hydrofluoric acid) or as a flux to lower the melting temperature in steel production. In the present study, a process was developed to produce a fluorite concentrate from a rare earth element (REE) bearing carbonatite.

The contents of fluorite, pyrite and calcite in the received fluorite concentrate are 93%, 4% and 0.5% respectively. This high content of calcite in the concentrate not only consumes sulfuric acid but also results in the generation of waste volume and heat energy during the furnace reaction of the acidification of the fluorspar …

Penalties can significantly reduce the value of copper concentrate. For instance, in this paper, the fluorine penalty deduction ranges from $7 to $54 for copper concentrate containing 0.1 to 0.57% fluorine ion, accounting for 0.3 to 2.4% of the net value of the concentrate before the penalty element deduction.

Processing of fluorite ores is the process of separating fluorite concentrate from fluorite ore. Fluorite, also known as fluorspar, has a chemical composition of CaF2, which is usually symbiotic with quartz, calcite, barite, and clay. Fluorite is mainly used as a slag-making flux for steel smelting in the metallurgical industry, and the ...

The maximum grade of fluorite concentrate for 200 g/t of SO and 100 g/t of SLS was 82.59% and 81.34%, respectively. The increase in SLS has reduced the fluorite concentrate grade due to increased recovery of other minerals. The lower fluorite grade in the sink phase with SLS is a function of higher fluorite recovery with SLS than SO.

The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% of solids, while 70 to 80% of the original water is recovered in the overflow as a clear liquid. The thickened pulp is then sent to ...
