Application of anionic polyacrylamide to circulating flocculation precipitation of water treatment in ore washing industry. During the washing process, the broken clay or colloid is rinsed with water. There are coal washing, mica powder, sand washing, fluorite, flotation, magnetic separation and other industries, the production needs a lot of water. In order to protect the ecological environment and an integrity of water sources, all industries have built water treatment recycling equipment in use, thus achieving the sustainable development goal of no waste water discharge.

Anionic polyacrylamide with different degree of hydrolysis has different applications in ore washing industry. Because the concentration of washing water is different, the particle fineness is different, and the anionic molecular weight is generally 16 million, and the hydrolysis degree is about 30. There is also the need for polyaluminium chloride as a coagulant. Because anionic polyacrylamide and coagulant aid can effectively reduce the moisture content of mud cake, mud cake with low moisture content is easier to be transported by car. In the industry where the circulating water of washing ore is not clear enough, some models with low anionic hydrolysis degree can be selected for incomplete flocculation.
