The Anionic Reverse Flotation Orthogonal Experiment for XuanLong Oolitic Hematite after Magnetic Roasting-Magnetic Separation

Article Preview

Abstract:

The concentrate of XuanLong oolitic hematite after magnetic roasting-magnetic separation are further refined. The anionic reverse flotation process is used. The three factors and three levels orthogonal experiments are designed to find appropriate reagent regime and shorten the time. The results demonstrate that the appropriate reagent regime and the effect of the various factors to flotation can be found through nine experiments. Final reagent regime is that the dosage of starch is 1000g/t, the dosage of lime is 3000g/t, the dosage of collector is 500g/t. The final concentrate grade is 63.83%.The recovery is 84.59%.
