Attention should be paid to polyacrylamide used in mineral processing wastewater

2022-12-17 15:47:00


Mineral processing wastewater is mainly from the dust removal water in the crushing process,ore washing wastewater, cooling water and so on.

Mineral processing wastewater is characterized by large amount of water, high content of suspended solids and many kinds of harmful substances. The harmful substances are heavy metal ions and mineral processing agents. Heavy metal ions include copper, zinc, lead, nickel, barium, cadmium, arsenic and rare elements.

The direct discharge of such waste water without treatment will have a damaging impact on the surrounding and downstream rivers, soil, farmland, wetlands and other areas, and ultimately endanger human health. Therefore, effective treatment and recycling of mineral processing wastewater is very important.


Concentrator special polyacrylamide series products are water-soluble linear polymer synthesized with high degree of polymerization. It is completely soluble in water and can dissolve quickly due to its microscopic form. Different types of polypropylene have different active groups, can condense different suspended particles, easy filtration and separation. The series of products are almost insoluble in any organic solvent, but are heavily soluble in water. It is widely used in many industries in the fields of flocculation, viscosity, bonding, scale inhibition, stable colloid, drag reduction, film formation, gel, biological materials and so on. The product has high viscosity and can effectively treat wastewater from concentrator.

Generally choose anionic polyacrylamide (generally weak anionic polyacrylamide and medium anionic polyacrylamide), molecular weight requirements in more than 15 million. Sometimes nonionic polypropylene such as strongly acidic water is used. Note: Different manufacturers, the same parameters of the product, the use effect is often very different. In short, the key is to choose the most cost-effective manufacturer of coagulant, strict operation in use, cost control.
