Selective flotation separation of fluorite from calcite by ...

01.07.2021  These selective depressants can, to a certain extent, achieve flotation separation of fluorite from calcite. However, these reagents have some defects in terms of selectivity, environment friendly, and complex process. Based on these current situations, it is very necessary to develop a depressant with high selectivity, environmental protection, wide pH condition, and low cost to improve the separation of fluorite

Selective flotation of scheelite from calcite and fluorite ...

01.03.2015  The flotation separation of scheelite from other calcium-containing minerals such as fluorite and calcite, is problematic, due to their similar solubility and the same active Ca 2+ site for interaction with anionic collectors (Rai et al., 2011). Thus, using a single type of collector is unlikely to achieve selective flotation of scheelite from fluorite and calcite.

Selective Flotation of Calcite from Fluorite: A Novel ...

The results demonstrated a high selectivity for the flotation of calcite from fluorite using this new reagent schedule. The best selective separation for a single mineral and mixed binary minerals was obtained when 200 mg/L of NaF, 50 mg/L of CA, and 6 mg/L of SOA were used at pH 9. In addition, a batch flotation experiment was carried out using a run-of-mine feed material. Selective separation was achieved with 85.18% calcite removal while only 11.2% of fluorite

Flotation tests on a single mineral and mixed binary minerals showed that the reagent schedule of CA 50 mg/L, NaF 200 mg/L and SOA 6 mg/L at pH 9 could achieve selective flotation of calcite from fluorite. Batch flotation tests on a run-of-mine fluorite–calcite ore indicated that, using this reagent schedule, the calcite removal rate could reach above 85% while fluorite has a loss rate of below 11%.

15.06.2019  Flotation tests were performed on a skarn ore to attain the selective separation of scheelite (CaWO 4) from fluorite, apatite, and silicates. Fluorite and apatite constitute common gangue minerals in scheelite ores. Due to their similar surface properties and good floatability, the separation of scheelite from fluorite is particularly difficult. These ores are usually processed at basic pH using
