Use of Chemically Modified Nanocelluloses in Flotation of Hematite and Quartz?
Best insight from top research papers
Chemically modified nanocelluloses, such as cellulose nanocrystals (CNCs) and silylated cellulose nanofibers (SiCNF), have been investigated for their potential use in the flotation of hematite and quartz minerals. In the case of hematite, a modified carboxymethyl cellulose was found to be an efficient depressant in reverse cationic flotation ^[Poperechnikova et al.]. For quartz, aminated CNCs were tested as collectors in flotation processes and were found to change the surface wetting properties of quartz and bubbles, either depressing or floating the mineral depending on the alkyl chain length, pH, and collector concentration ^[Kimpimäki]. SiCNF, on the other hand, showed promising results as a selective flocculation agent for sulfide minerals, forming flocs with sulfide particles but not with quartz ^[Braga de Carvalho et al.]. These studies highlight the potential of chemically modified nanocelluloses in improving the flotation performance of hematite and quartz minerals.
