floatation separation
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. 1Hydroxyethylidene1,1diphosphonic acid (HEDP or H4L ...
