Utilization of novel surfactant N-dodecyl - ScienceDirect
Flotation recoveries of quartz and hematite, which are 93.12% and 7.23%, could be obtained when starch concentration is 13.33 mg/L. Thus, starch signally depresses the float of hematite and has little impact on the flotation of quartz, so the separation of hematite and quartz could be successfully achieved with a certain amount of starch [18].
