· Fatty acid collectors can float both of calcite and fluorite, therefore, it is needed to adjust the PH value of slurry. Practice shows that the PH value has a great impact on the flotation. When the PH value in the range of 8-9.5，the fatty acid collectors can display function both of the fluorite and calcite.

· The anionic reagents have been used in the flotation separation of fluorite from barite, such as sodium oleate NaOl and sodium petroleum sulfonate SPS [8,9]. These anionic collectors are non-selectivity for the fluorite and barite, thereby they need to be used with the depressant to inhibit the flotation of barite.

Abstract. CaF 2 , as an important strategic mineral source, is usually separated from calcite by the common froth method, but this separation is still not selective enough. The development of a selective and/or depressant is the key to achieving high selective separation. 1-Hydroxyethylidene-1,1-diphosphonic acid HEDP or H 4 L is widely used as an environmentally friendly …

· The 4:1 collector mixture 733+MES with WG 3.0 × 10 −3 mol/L at pH 10 could achieve selective flotation of scheelite from fluorite and calcite. With a lower cost, lower dosage, higher selectivity and higher tolerance against water hardness, the collector mixture 733+MES exhibits great potential for industrial application in scheelite flotation.
