Abstract
An improved process for the enrichment of bauxites with unfavorable textures and low qualities via flotation and carried out after selective agglomeration. According to the process of the invention a water-soluble prepolymer of low chain length is added to the slurry as flocculating agent, thereafter the polymerization is started again by heating the slurry and/or adjusting its pH and/or adding a catalyst thus converting the polymer chain fragments adhered onto the gangue with high surface activity into a cross-linked resin, and finally the slurry is subjected to flotation in the presence of a conventional flotation aid.
