In this regard the flotation of barite type fluorite generally needs to adjust the pH value of the slurry through a mixing process and Na2CO3 and use oleic acid and water glass as collectors and inhibitors to obtain a mixed concentrate of fluorite and barite Ore and then flotation to separate barite and fluorite

the anionic flotation of fluorite from barite using

The main component of fluorite is CaF2 so fluorite is the industry resource of F Fluorite has a rich color usually grows with scheelite phosphorite pyrite blende quartz dolomite and other minerals Flotation separation for the fluorite beneficiation is difficult for similar characteristics between fluorite and pyrite barite

the flotation separation of fluorite from calcite using

Bastnaesite is a chief natural source of light rare earth elements LREEs The effective depression of Cacontaining minerals such as fluorite and calcite in bastnaesite flotation system is normally difficult and it is imperative to exploit more environmentallyfriendly depressants which can inhibit these gangue minerals simultaneously Hence we employ citric acid H SUB 3 SUB Cit a

the improvement effect of dispersant in fluorite flotation

Fluorite is an important nonmetallic mineral resource and the main source of fluorine in the industry There are three kinds of processing processes of fluorite hand separation gravity separation and flotation separation Among them hand separation and gravity separation are mostly used as auxiliary separation and preseparation while flotation separation is the main method

flotation separation of fluorite from calcite using

It prohibits fluorite flotation at pH 6 and thus benefits the reverse flotation Fluorite can be activated at pH 8 and then enriched by flotation Thus pH is the key parameter controlling the efficient separation However the cost of organic phosphonic acid is

pdf improving fluorite flotation from ores by dispersion

Whereas a metallurgicalgrade fluorite is obtained by gravity and magnetic separation methods flotation is the major concentration process for the production of acidgrade fluorite Selective
