Settlement and separation of red mud is an extremely complex physical and chemical process.Bayer method dissolution of pulp from the red mud is red mud and the formation of sodium aluminates solution suspension.Due to red mud formed red mud particles and solution exists the complex physical and chemical effects, phase composition of red mud, grain fineness distribution, surface morphology of red mud particle and solid content of red mud liquid, liquid ingredients, red mud fluid femperature and etc.Have significant effects on the processing of settlement and separation of red mud.
If you can select one appropriate flocculating agent, the application of flocculant technology can make solid-liquid separation speed improve greatly, and can reduce the size of the equipment.The mechanism of polymer flocculant is that, the effectively flocculation between particles through absorption and bridge.Surface absorption and charge neutralization can form a "big particle", making he settling speed greatly.Different stripping mash has different settling property.We must choose the appropriate polymer flocculant according to the test results, so as to realize red mud separation efficiently.
Effect:
Flocculating powerfully, fast and steady flocculation small and tight flocks, good resistance to shear reduce effectively seston in acid aluminum and improve settling tank capacity
Improve clarity and the quality of the overflow low liquid-solid ratio prevent red mud inflation :Have little influence in temperature, pH value
