摘要: In this work, the adsorption behavior of dodecylamine (DDA) on scheelite and calcite mineral surfaces were investigated by molecular dynamics (MD) simulation, zeta potential measurement, AFM observation, contact angle flotation test. The results implied that, different DDA was mainly attributed to cationic species RNH3 + DDA. neutral RNH2 complex precipitates produced reactions between anionic released both surfaces, also played important roles. a solution (1 � 10 4 mol/L, pH 7.5–8.0), handful adsorbed through N–Ca bonding hydrogen hydrogens –NH2 group surface oxygens. On positively charged surface, moderate number CO3 2�
