flotation fluorite sarcosine

(PDF) Mechanism of collector adsorption in fluorite flotation

Selective flotation of fluorite from calcite presents many problems because the two minerals have the same cation, Ca++, in their crystal lattices. Oleoyl sarcosine FTIR 1418–1380 Chemical 14.

Investigation of Langmuir monofilms and flotation

Apr 01, 1998· The flotation recovery of fluorite is enhanced by mixed adsorption of C 12 sarcosine and C 12 amine collectors. The best recovery in flotation is achieved by 60:40 mol% C 12 sarcosine and C 12 amine. In contrast, the second reagent regime, C 12 acid and C 12 amine could not realize this strong increase in recovery after adding the co-collector.

Replacing Petrov's process with atmospheric flotation

Jan 01, 2020· Although oleoyl sarcosine shows good selectivity in the flotation of fluorite and siliceous scheelite ores (Ozcan and Bulutcu, 1993, Ozcan et al., 1994), the selectivity is not adequate for a low-grade calcite scheelite ore.

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

Beneficiation of fluorite by flotation in a new chemical

Jul 01, 2003· Also, fluorite flotation could be improved by using effective depressants when fatty acid is used as collector. For example, acidized sodium silicate was reported to depress calcite strongly in preference of fluorite at ambient temperature, leading the fluorite flotation to be achieved at a lower temperature (Zhou and Lu, 1992).
