2006-2-28 · Arsenide depression in flotation of multi-sulfide minerals . United States Patent 7004326 . Abstract: A mineral separation process includes wet-grinding the ore to liberation of minerals, oxidizing the slurry using air, hydrogen peroxide or other oxidants and floating the valuable minerals at a pH between about 9.0 and 10.0 with a xanthate as
2009-10-1 · The flotation response of gersdorffite has been determined in a series of batch flotation tests in which a sulphide sample containing about 76% gersdorffite was floated from mixtures with quartz. Using xanthate as collector, the arsenide floated strongly at pH 9, irrespective of whether lime, sodium hydroxide or sodium carbonate was used as pH
