Setting flocculant for the red mud of alumina

1. Product characteristics

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 cintent of red mud liquid, liquid ingredients, red mud fluid temperature and etc, have significant effects on the processing of Settlement and Seperation 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 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 the settling speed greatly. Different stripping mash has different settling property. We must choose the appropriate polymer flocculant accroding to the test results, so as to realize red mud separation efficiently.

3. 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

4. Instruction for use

Prepare·approximately 1% alkal solution

Keep it at the temperature of 50℃or so, put in the diluted settling and washing flocculant by 0.3%-0.5%

Let for half an hour to dissolve completely, improving effect
