| Abstract: |
| Sodium silicate is a common inhibitor,and often used to inhibit quartz,calcite and silicate gangue. As a selective inhibitor of calcium gangue,in the scheelite selection process, sodium silicate often used in combination with other agents.In order to explain the inhibition mechanism of sodium silicate on scheelite in scheelite selection process.On the basis of flotation test,using infrared spectroscopy,analysis the position change of surface characteristics of the peak absorption band with the wavenumber,with and without sodium silicate of single minerals, scheelite, calcite and fluorite,verified the accuracy of the flotation test from the angle of mechanism. |
