Role of silica and alumina content in the flotation of
10/03/2016· Flotation experiments were carried out with both samples i.e., the high alumina and high silica iron ore, using dodecylamine DDA as the collector. The flotation response in terms of Fe grade of the concentrate is shown in Fig. 7. The effect of DDA concentration using soluble starch 500 g/t as the depressant was studied at a pH around 7.5.
