performances of two flocculants and their mixtures for red mud dewatering and disposal based on mineral paste production

Performances of two flocculants and their mixtures for red mud dewatering and disposal based on mineral paste production

Red mud is a mineral residue resulting from the caustic digestion of bauxite ore in the Bayer process to produce alumina. Research shows that the chemical and physical properties of red mud depend on ore sources, that is, the bauxite rock mineralogy, and the refining processes (Hua et al., 2017; Liu et al., 2014).

Investigating bauxite residue flocculation by hydroxamate and polyacrylate flocculants utilising the focussed beam reflectance ...

Polyacrylate and hydroxamate flocculants are commonly used to aid solid¨Cliquid separation of bauxite residue from pregnant liquor in the Bayer process. This study presents the direct examination of the bauxite residue flocculation with polyacrylate and hydroxamate flocculants, using the focussed beam reflectance measurement (FBRM) probe to monitor aggregate dimensions.
