arsenide Depression In Flotation Of Multi Sulfide Minerals

US7004326B1 Arsenide depression in flotation of multi

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 collector, and a combination of a polyamine and a sulfur containing species as depressants for arsenide minerals.

Rejection of arsenic minerals in sulfide flotation — A

2009-10-1  The oxidation rate of arsenic minerals and non-arsenic minerals has been compared in a series of papers to explain the selective flotation of arsenic minerals from other sulfide minerals. According to Iwasaki et al. (1988),nickel arsenide (Ni 11 As 8 ) is much more easily oxidized than pyrrhotite, pentlandite, chalcopyrite and cubanite.

The flotation of niccolite — A single mineral study

2010-2-19  The flotation response of niccolite at pH 9 is shown in Fig. 1 for a series of tests in which the mineral was ground in an iron mill and then floated for 8. min in the presence of increasing amounts of ethyl xanthate collector.. Although niccolite recovery increased as the collector addition was raised, the flotability in all tests was poor.

The flotation of gersdorffite in sulphide nickel systems

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
