Abstract: The paper analyzed the rich phosphate rock resources and the traditional methods for phosphate flotation in China, elaborated the important significanceof separating bed phosphate by separating bed separator.It designed a test bed separation system.The test was executed by the coarse granularity of 0-3.0mm Yichang Phosphorite Ore slime in experimental study.It analyzed the rule of separating phosphate ore by teetered bed separator.The optimum working point of sorting was found and the contrast curve analysis was carried out.It demonstrated significant economic benefits and broad market prospects.
