Froth flotation of rutile – An overview - ScienceDirect

Mar 15, 2021  The recovery of pure rutile mineral flotation at the optimum conditions reached 97.5%, and that one for the mixed ore flotation, was higher than 97% with a rutile content of over 80% being achieved (Sun et al., 2010). By the way, it was reported that TPRO can chemically absorb onto rutile surface in the form of chelation, and the possible product is expected to a stable five-membered ring chelate.
