The use of polyacrylamides in mineral processing

High molecular weight, water-soluble polyacrylamides and related products have for many years, been used successfully within the Mineral Processing Industry to aid solid-liquid separation. This traditional area of use is discussed with particular emphasis being placed upon the more recent innovations in terms of equipment and modifications, in

The effect of polysaccharides and polyacrylamides

The acknowledged chemical nature of the interaction between dextrin and sulphide mineral surfaces (involving complexation between hydroxyl groups on the polymer and metal ion sites on the mineral, see Liu and Laskowski, 1989, or Raju et al., 1997) could equally result in some form of passivation, reducing the degree of oxidation with time and

influence of adsorbed polysaccharides and polyacrylamides

Influence of adsorbed polysaccharides and polyacrylamides

Historically, the choice of a polymer to depress a particular gangue mineral in flotation has been based on empirical testing. The trend in recent times has been to specifically design polymers for this purpose as well as for other areas of mineral processing (Chen et al., 2003). The approach followed has been to tailor the molecular weight and

Depressing effect of flocculants on molybdenite flotation

Polyacrylamides, the most common commercial flocculants, as shown in Fig. 1, are to some extent anionic (expressed as degree of anionicity), and so they can also be treated as co-polymers of polyacrylamide and polyacrylic acid.High molecular weight PAMs with a degree of anionicity in the range 20–30 are claimed to be the most efficient in thickening tailings (Michaels, 1954, Xu and Cymerman
