Floatability of apatites and gangue minerals of an igneous ...

Nov 01, 2008  The presence of different apatite types is characteristic of igneous phosphate deposits. The flotation performances of primary and secondary apatites occurring in phoscorites, weathered phoscorites and pyroxenites were investigated. As a contribution towards the understanding of the behaviour of the flotation system, the major gangue minerals ...
