ABSTRACT:
Rutile is recovered from copper ore tailings by means of a froth flotation process comprising: (a) flotation of sulfides and carbonates at a pH of about 9 to 10, using sodium isopropyl xanthate and sodium oleate as collectors, and detrine as rutile depressant, and (b) flotation of rutile from the resulting tailings at a pH of about 2 to 3, using hydrofluoric acid as a rutile selectivity-assisting agent and water-soluble petroleum sulfonate as rutile collector.
