Abstract:It is important to develop a green and efficient removal method for the clean utilization of ilmenite concentrate. In this paper, the effects of oxidant type, dosage and number of stages on the reagent removal rate of concentrates are studied using oxidative reagent removal process for ilmenite concentrates. Scanning electron microscopy (SEM) and infrared spectroscopy are used to analyze the effects of oxidation reagent-removal mechanism. The results show that hydrogen peroxide is an effective reagent for the removal of ilmenite concentrate, which can oxidize and resolve the sodium oleate adsorbed on the surface of ilmenite. When the dosage of hydrogen peroxide in the first stage and second stages is 1100 g/t ~1200g/t respectively, the total reagent removal rate of ilmenite flotation concentrate is 71.97%. This study can provide some reference for the removal of reagent of flotation concentrate.
