Fluorite is a nonrenewable mineral used to produce anhydrous hydrofluoric acid (AHF) and aluminum fluoride. The demand for low-grade 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 extraction of lithium into solution is practically independent of the initial alkalinity of the solution and is 86–93%, in contrast to the extraction of Al 2 O 3. Thus, a change in concentration of Na 2 O from 350 to 450 g/L leads to an increase in Al 2 O 3 extraction from 78.8 to 94.7% at the α k = 18, and at 450 g/L the maximum ...
