Calcite Flotation in Potassium Oleate/Potassium

2015-7-2 · The flotation of calcite at pH 7.0 was suggested as being due to precipitation of the added soluble phosphate as hydroxyapatite in solution and/or on the mineral surface and the subsequent flotation of calcite as if it were an apatite mineral. Effect of KH 2 PO 4 on the Electrokinetic Properties of Calcite

New Process for Calcite Flotation from High Calcium

The raw ore of high calcium and carbon-type vanadium bearing stone coal in Hubei province contained CaO of 6. 26%,C of 13. 44%,V2O5of 0. 71%. The vanadium occurred in mica and minerals was severely contaminated by carbon. For the high acid consumption and cost in leaching because of the existence of calcite,the technique of combining flotation with hydrometallurgy was used.

2019-3-5 · As a result, the removal of calcite by flotation from the decarburized stone coal is not as good as expected. The flotation behaviors of muscovite and calcite have been widely reported [ [19],[20],[21],[22] ], but the flotation separation of these two minerals in solution with respect to the flotation of decarburized stone coal which contain a large number of metal ions are still unclear.
