High molecular weight polymers with side-chain salicylic acid groups for the clarification of alkalis from the bayer - the method

摘要

A high molecular weight, water-soluble polymer comprising pendant salicylic acid groups and having a weight average molecular weight of at least about 2,000,000 daltons and use of the polymer for clarifying red mud-containing liquors generated in the Bayer process for the recovery of alumina from bauxite.
