Alumina red mud sedimentation flocculant

Sedimentation and separation of red mud is an extremely complicated physical and chemical process. The Bayer process dissolving pulp is a suspension formed by red mud and sodium aluminate solution. Due to the complex physical and chemical interactions between the red mud paricles and the solution, the phase composition, distribution, surface morphology of red mud particles solid content of red mud slury, liquid phase composition, red mud slurry temperature, etc. all have significant effects on the sedimentalion and separation process of red mud slurry.

By adding specific flocculant can greatly increase the settle speed of solid-liquid separation. The mechanism of high-molecular fiocculantslies in the effective coagulation between the red mud particles through adsorption bridges, surface adsorption and charge neutralization, and the formation of "large particles", which greatly accelerates the settling velocity. Different dissolution ore pulps have different properties, and the appropriate polymer focculants must be selected through experiments before achieving high efficient separation of red mud on site.

Effect :
Strong fiocculation, stable flocculation process

The formed flocs are small strong and anti-shear

Effectively reduce the content of suspended matter in the aluminate liquid and increase the productivity of the subsider

Improve clarity and overfow quality

Underflow liquid-solid rafio is low

Prevent red mud from swelling

Less affected by iemperature and PH change.
