| Abstract: |
| According to the difference of the mineral property, an investigation is made of the floatability and process flowsheet of a certain fluorite ore. A kind of depressant is found base on lots of works. A fluorite concentrate grading of 95 % CaF2 and assaying of 3 % CaCO3 and a recovery of 76.61% are obtained by processing using a single flotation flowsheet consisting of one stage grinding-two stage roughing-two stage scavenging and five stage cleaning. |
