【 摘 要 】

The aim of this this paper was to investigate the effectiveness of flotation process depending on the changeable dose of reagents and variable speed of rotor in flotation device. HPGR crushing products were used as a feed in all flotation tests. Efficiency indices, along with Fuerstenau curves, were determined for each test. Both rotational speed and the dose of reagent have affected the flotation results in a lower degree that expected. However it could be possible to determine the optimal dose and rotational speed of rotor that increase the effectiveness of flotation process.
