Effect and mechanism of siderite on reverse flotation of

The effects of siderite on reverse flotation of hematite were investigated using micro flotation, adsorption tests, and Fourier transform infrared spectroscopy. The flotation results show that interactions between siderite and quartz are the main reasons that siderite significantly influences the floatability. The interactions are attributed to dissolved siderite species and fine siderite

Beneficiation of High‐Phosphorus Siderite Ore by Acid

Dec 29, 2016· With 12% dosage of alkaline oxide additive (Na 2 CO 3:CaO = 1:1), the reduction of siderite is reinforced. The iron particle size in reduced ore is coarse and the diffraction intensity of metallic iron increases obviously. The reinforcing affect is mainly caused by an increase of the reducing reaction activity of FeO.
