Abstract

The associated ore with fluorite and barite in Yunnan was studied to solve the technological problems that floatability was similar and separation of fluorspar with barite difficult. The results show that the grade of barite in the ore is 44.38% and that of fluorite 20.21%, and the chief gangue mineral is quartz. After comparison of some trial processes, the mixed flotation process of fluorite and barite is ultimately adopted. Saponified sodium oleate is used as collector in bulk flotation. The mixed flotation process of floating fluorspar and restraining barite is then taken with aluminum sulfate as inhibitor of barite in order to assure the floatability of fluorspar. After the closed circuit flotation experiments, the grade of fluorite concentrate is 96.13% and the recovery rate 88.74%, and the grade of barite concentrate is 87.65%, and the recovery rate 97.78%.
