Application Study of New Low Temperature Resistant Collector HY-F in a Fluorite Mine
In order to investigate the adaptability of the new low-temperature collector HY-F to a fluorite mine,a flotation test was carried out on the basis of process mineralogy.The results showed that compared with common oleic acid and oxidized paraffin soap,the new low temperature resistant collector HY-F was less affected by pulp temperature and showed better low-temperature resistance.Under the low-temperature slurry environ-ment(5℃),fluorspar concentrate with CaF2 grade of 98.41%and CaF2 recovery rate of 87.87%can be obtained,compared with the ambient tempera-ture slurry environment(20℃),its concentrate grade and recovery only decreased by 0.44 percentage point and 5.48 percentage point.It shows that the new low temperature resistant collector HY-F has good low temperature resistance and good adaptability to the fluorite mine,and has certain process guidance value and application prospects.
