Anatase, Ti (1−X) Fe X O 2, with X = 0 to, is a common ironbearing impurity in sedimentary kaolin that can be unresponsive to kaolin beneficiation processes, such as magnetic separation, due to its extremely fine particle size (< µm), or chemical bleaching, because of its chemical stability. Described here are selective flocculation ...
The selective flocculation tests carried out on 1:1 iron oxide/kaolin mixtures using parent polyacrylamide, polyacrylic acid and the modified polyacrylamide, confirm the possibility of enhancing selectivity through introduction of iron chelating functional groups in commercially available polymers.
This process consists of titanium impurities removal by selective flocculation, using anionic polymers of medium and high anionicity. The objective of this paper was to increase brightness of the kaolin clay from Northern Brasil through titanium impurities removal by selective flocculation.
