Alumina red mud special PAM is a polymer floctant optimized for red mud settling characteristics, usually anionic or non-ionic, because red mud slurry is mostly alkaline, and the particle surface is negatively charged, the appearance of white powder or colloidal liquid, easy to dissolve in water.
Features and advantages
Efficient settlement: shorten the red mud settlement time (such as the traditional process takes 4-6 hours, can be shortened to 1-2 hours after the use of PAM), improve the production efficiency of alumina.
Low dosage and high cost performance: the dosage of PAM per unit red mud is usually 5-20 g/t, and the cost is lower than that of traditional inorganic floctics (such as aluminum sulfate).
Environmental protection coordination: reduce the storage volume of red mud and reduce the risk of lye leakage; The wastewater reuse rate can be increased to more than 80%, in line with the requirements of clean production.
Convenient peration: fast dissolution speed (powder PAM dissolution time is about 60-90 minutes), suitable for automatic dosing system.
