STUDYING THE ADSORPTION MECHANISM OF COPPER AND IRON REAGENTS ON THE SURFACES OF CASSITERITE MINERALS BY CALCULATING ADSORP TION CAPACITY AND MEASURING RADICAL ELECTRIC NEGATIVE

本文研究了钢铁试剂在锡石表面的作用机理。通过吸附量的测定证明,铜铁试剂在锡石表面上的吸附等温线符合Lagmuir等温式,由此证明捕收剂在锡石表面形成单分子层的化学吸附。通过电负性的计算结果讨论进一步证实,铜铁试剂在锡石表面上的吸附是以O,O原子形成的五员螯合物。

The action mechanism of copper and iron reagents on the surfaces of cassiterite minerals is studied By calculating the adsorption capacity, it is found that the adsorption isothermal lines of Cu-Fe reagent ons the surfasec of cassiterits minerals are in agreement with the Lagmuir isothermal line, whereby the authors prove that collectors form monomolecular layer chemical adsorption on the surfaces of cassiterite minerals By calculating the electric negative,the authors proves the adsorption leads to the fosmation of 5-element chelates in the form of O,O.
