Selective flotation of scheelite and calcite

Flotation of calcite as a function of pH is shown in Fig.3. Flotation of calcite has not been studied in the acid range as it is possible for the calcite to react with the acid with the formation of micro bubbles of CO2 on the surface of the mineral and make it float. Floatability of calcite shows a minimum at pH 9.5 and increases with

Reverse Flotation Separation of Fluorite from Calcite: A

Fluorite (CaF2), as an important strategic mineral source, is usually separated from calcite by the common froth flotation method, but this separation is still not selective enough. The development of a selective collector and/or depressant is the key to achieving high selective separation. 1-Hydroxyethylidene-1,1-diphosphonic acid (HEDP or H4L) is widely used as an environmentally friendly
