polyacrylamide is widely used as a flocculant or filter aid in mining minerals such as gold, silver, copper, aluminun, iron, tin, coal, lead, zinc. For this industry, the molecular weights of the anionic polymers will range from low to very high. These polymers are used to separate mineral particles of different sizes and densities and separate them from the water they are suspended in.
