Which polymers are used in Mineral Processing & Hydrometallurgy?

The vast majority of synthetic polymers used in mineral processing and hydrometallurgy are based on acrylic chemistry. The polymers are very versatile in terms of molecular architecture and as such have found many uses in the industry. Since their inception in the 1960s, rapid growth in their use has been witnessed.

What are coagulants based on polyacrylamide?

5.1. Flocculants and coagulants Flocculants based on polyacrylamide represent the largest category of organic reagents, Pearse (2003). The polyacrylamide molecule can be tailored to virtually every mineral processing solid–liquid separation condition.

Which amine is used as a collector for silicate minerals?

Both fatty and ether amines and diamines are used as collectors for silicate minerals. Amine condensates resist high sulphate levels and are used in phosphate flotation processes where roughing collector fatty acid is scrubbed from the surface with sulphuric acid for subsequent reverse cleaning with the amine.
