Mineral Separation Flocculant

Product introduction

The mineral separation flocculant takes important part in solid-liquid separation process of beneficiation. It can not only separate minerals and ores, but also can be used as a flocculant in wastewater treatment, as well as sealing mining pipelines.

The special grade of polyacrylamide offered by CHUNDI is oriented to different mineral dressing needs. They have good stability, strong adsorption and bridging ability, good flocculation effect, fast settle speed, and good resistance against high temperature and salinity.

Application areas

Iron, copper aluminum, nickel, gold, lead-zinc, phosphate, coal mine, titanium, titanium dioxide, tungsten ore, etc.


Alumina Red Mud Sedimentation Flocculant

Product Introduction

Sedimentation and separation of red mud is an extremely complex 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 particles and the solution, the phase composition, distribution, surface morphology of red mud particles, solid content of red mud slurry, liquid phase composition, red mud slurry temperature, etc. All have significant effects on the sedimentation 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 flocculants lies in the effective coagulation betweeen 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 flocculants must be selected through experiments before achieving high efficient separation of red mud on site.

Product Effect

1.Strong focculation, stable flocculation process

2.The formed flocs are small strong and anti-shear

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

4.Improve clarity and overflow quality

5.Underflow liquid-solid ratio is low

6.Prevent red mud from swelling

7.Less affected by temperature and PH change
