通过吸附试验、X-射线光电子能谱(XPS)和俄歇电子能谱(AES)、浮选试验,系统地研究了糊精在萤石和方解石表面作用行为,结果发现,方解石经糊精作用前后GaLMM俄歇参数变化值为0.80eV,变化显著,这说明糊精与方解石表面作用为化学键合;而萤石经糊精处理前后CaLMM俄歇参数变化值为-0.20eV,变化不明显,说明糊精与萤石表面化学作用很弱,更接近物理作用-氢键作用;浮选试验结果证实了测试结果可靠性。
The effect of dextrin on the surface of fluorite and calcite was systematically studied by adsorption test, X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES) and flotation test. The results showed that the effect of dextrin on the surface of fluorite and calcite was studied. GaLMM Auger parameter change value of 0.80eV, significant changes, indicating that the dextrin and calcite surface effect for the chemical bonding; and fluorite before and after the dextrin treatment CaLMM Auger parameter change value of -0.20eV, the change was not significant, This shows that the dextrin and fluorite surface chemistry is very weak, more close to the physical role - hydrogen bonding; flotation test results confirm the reliability of test results.
