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.

对白云石和胶磷矿的Zeta-电位测定、红外光谱分析MG药剂在矿物上面的吸附情况、紫外-可见吸收光谱测定矿物上MG的吸附量等，研究了MG药剂反浮选白云石的浮选作用机理，表明在弱酸性条件下，由于白云石表面荷正电而胶磷矿表面荷负电，带有羧基和羟基官能团的MG药剂更容易吸附在白云石上，使其周围吸附有大量的MG负离子，而MG负离子的另一端为烃基，这就改变了白云石的疏水性，使其矿粒容易附着于气泡上浮。
