The flotation mechanism of MG reverse-floating dolomite was studied by measuring the Zeta-potential of collophanite and dolomite, Infrared Absorptions Spectra analysing the adsorption of MG onto the minerals surface, ultraviolet- visible light absorbing spectrum calculating the amount of MG which was adsorbed onto the minerals surface. These researches showed that MG was more easyly adsorded onto the surface of dolomite in feeble acidic solution because of pure dolomite charges positive as well as pure collophanite charges negative. Therefore, a lot of MG negative ions was adsorded onto dolomite, and that MG negative ions contained hydrophobic group, the hydrophobicity of dolomite was modified, the grains of dolomite were adhered to air bubble and float with them.
