Flotation Of Cassiterite With Modified Fatty Acids Gabon

Abstract the flotation and surface interaction of cassiterite with salicylhydroxamic acid have been investigated in this paper the results showed that recovery of cassiterite with salicylhydroxamic acid was high at a neutral ph with the maximum recovery occurring at ca ph 65 when the size of cassiterite is less than 74 μm coarse particles showed better flotability than the fine ones.

Study On The Effect Of Fe3 On Zircon Flotation Separation

In theory the flotation of both zircon and cassiterite should be enhanced in the presence of fe 3 in contrast the flotation of cassiterite was decreased which can be inferred to be due to the adsorption of feoh 3 s on cassiterite surfaces while feoh 3 s had the similar zeta potentials to that of cassiterite measured with fe 3 alone
