The case of fluorite flotation direction

flotation separation of fluorite from calcite usingmay 01, 2018· generally, fluorite is separated from calcite via flotation by using fatty acids (mainly sodium oleate) as collector and water glass (or modified water glass) as depressant in actual production ( peng et al., 2014, zhou and lu, 1992, zhou et al., 2013 ). despite its low price and high inhibition, the water glass dosage is high."reverse flotation separation of fluorite from calcite afluorite (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. 1hydroxyethylidene1,1diphosphonic acid (hedp or h4l) is widely used as an environmentally friendly reverse flotation separation of fluorite fromjul 26, 2018· the flotation tests of binary mixed minerals showed that the selectivity of snls for fluorite was higher than that for scheelite at ph 9.0 and a low dosage of 1.1 ×flotation studies of fluorite and barite with sodiumjan 01, 2019· sps was used as a collector to study the flotation behavior of fluorite and barite with shmp as a depressant. the flotation results showed that sps performed well in an alkaline pulp even at a low temperature (5 °c), while the flotability of fluorite and barite were almost the same. at ph 11, the presence of shmp obviously depressed fluorite rather than barite and shmp exhibited good selective inhibition to fluorite.improving fluorite flotation from ores by dispersionjul 01, 2006· accordingly, a study for improving the fluorite flotation by dispersion processing has been carried out in this work. the fluorite flotation is performed by using oleic acid as the collector and quebracho as the depressant, which is a commonly used chemical scheme for fluorite flotation (crozier, 1992, raju and prabhakar, 2000).flotation research of a fluorite ore academicfocusabstract separating fluorite from quartz and calcite by forth flotation can be both in weakacidized(p h 6.0) condition and weak alkali(p h 9.0) condition.the experiment results have shown that zn so4 can decrease the depression that water glass works on the fluorite,and acidized water glass has a selective inhibition on the silicate minerals.the close flowsheet protocolled in thefluorite (fluorspar) flotation processthe sulfide ore contained in fluorite (fluorspar) is floated with xanthate collector, and then fatty acid collectors float fluorite (fluorspar). in flotation of fluorite (fluorspar), it can be also feasible to add a small amount of sulfide mineral to inhibit residual sulfide mineral, and ensures the quality of fluorite (fluorspar) concentrate.
