Experimental Research on Processing of a Quartz-barite Fluorite Ore in Henan Province
-
Abstract
The fluorite in a quartz-barite fluorite ore from Henan province has uneven dissemination sizes.Most of the coarse-grained fluorite particles are closely associated with quartz and barite,and part of the fined-grained fluorite particles are wrapped by quartz and feldspar.In order to rationally exploit this fluorite ore,an experimental research on removing silicate and barite were conducted.The results showed that the fluorite concentrates with a yield of 35.92%,CaF2 grade of 97.78% and CaF2 recovery of 79.08% could be obtained by adopting the method of "roughing in weak basic environment to desilicification,cleaning in weak acidic environment to remove barite" and the process of "two-stage grinding,two-stage roughing,one scavenging,seven-stage cleaning and the middlings returning in order" with using KDP as the inhibitor of barite.The contents of SiO2 and BaSO4 in concentrate were 0.60% and 0.38%,respectively.Compared with the conventional closed circuit (one-stage grinding,one-stage roughing),a higher grade of fluorite could be achieved with barely changed recovery. -
