Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available. In this …

In summary, we proposed a strategy that combines simultaneous grinding and surface modification in ball-milling with controlled gas-liquid microdispersion in the …
This novel flotation process was developed for the recovery of tungsten minerals in the Shizhuyuan Mine in China, where the normal-temperature flotation of tungsten minerals was investigated as a method to treat scheelite-calcite-fluorite-type ores as an alternative to the conventionally employed Petrov process (Han et al., 2017a, Han …
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 …
The raw mineral was ground in the ball mill until the content of −44 µm particles exceeded 87%. The pulp density was adjusted to 33% during flotation, and the flotation time was 3 min. ... Further development of fluorite flotation from ores containing higher calcite contents with oleoylsarcosine as collector. Int. J. Miner. Process., 30 ...
This article begins with introducing the deposits and unique physical and chemical properties of fluorite from the perspective of the crystal structure. It is followed by a systematic …
Fluorite and scheelite, which are strategic calcium-bearing minerals, have similar active sites (Ca2+); as a result, the efficient separation of the two minerals is still one of the world's most difficult problems in the field of flotation. In this work, N-decanoylsarcosine sodium (SDAA), a non-toxic and low-cost amino acid surfactant, was …
Flotation is widely used in the purification of fluorite from other gangue minerals (Song et al., 2006, Wang et al., 2014). However, gangue minerals such as calcite and barite may cause problems in the flotation of fluorite because of their similar flotation properties (Zhu et al., 2018). Therefore, physical processes (e.g., magnetic or ...
