Effect of Simulated Water from Diaojuntai Concentrator on the Iron Mineral Flotation in Qidashan Concentrator

The effect of starch, lime, sodium hydroxide and RA-315 contained in the reclaimed water from wiling pond of Diaojuntai concentrator on the flotation process of Qidashan concentrator were inveshgated in the laboratory. The results show that the main fator influencing the flotahon process was pH value of the reclaimed warer. The presenc of stareh and RA-315 also influences the process, but this influence can be reduced to acceptabe level by decreasing the dosage of collector used. The reclaimed water from the tailing pond of Diaojuntai concentrator can be direchy used as flotation water in Qidashan concentrator.
