CN110743715A Interface-strengthened fluorite flotation
The invention belongs to the technical field of mineral separation, and particularly relates to an interface-enhanced fluorite flotation technology. By adding oleic acid and sodium carbonate in situ in the ball milling tank, the surface potential of the mineral powder is adjusted to effectively prevent fine particles from agglomerating, and the adsorption of oleic acid on the surfaces of

The role of flotation agent (2) The key fluorite flotation of scheelite is to find an efficient inhibitor. The single mineral test, mixed ore test and actual ore sorting results show that citric acid can effectively inhibit fluorite in the flotation separation of scheelite fluorite, thus achieving the separation of scheelite fluorite.

Froth flotation of fluorite: A review ScienceDirect
2021-4-1 The best pH for fluorite flotation in either pure water (collectorless flotation) or in the presence of surfactants (froth flotation) ranges from 7 to 11 [ [50], [51], [52], [53] ]. It was also shown that pH 9 is usually selected as the most suitable pH regardless of flotation reagents [

Abstract Data on the flotation recovery, surface pressure and zeta potential at different surfactant concentrations and at pH 6.5 and 10.0 are presented for the n-alkylammonium chloride/fluorite system. Correlation of the results suggests a major role of the collector adsorption at the air-liquid interface in determining the flotation response. Attachment of particles to bubbles has been

Froth flotation of fluorite: A review PubMed
Finally, the most widely seen fluorite-flotation cases, including separation of fluorite from quartz, calcite, barite, and sulfide, are summarized individually. The present review sheds new light on the deep understanding of fluorite flotation, the future synthesis of reagents, as well as their schemes in practical use.
