Process for rutile flotation by means of N-benzoyl-N- phenylhydroxylamine as a selective collector

摘要

A process for rutile flotation from rutile ores associated with iron containing components, in which process an alcoholic solution is employed of N-benzoyl-N-phenylhydroxylamine as a flotation collector of rutile. This process is especially suitable for rutile separation by flotation from rutile-hematite ores, with the use of said selective collector at pH values between 1 and 2.5.
