A modification in the flotation process of a calcareous–siliceous phosphorite that might improve the process economics

•Low-grade phosphate ore was upgraded using fatty acid flotation process.•The main gangue minerals are calcite and quartz.•Acidic flotation of calcite was conducted without phosphate depressant.•Phospho-concentrate assaying 30.54% P2O5 was obtained. The amenability of a low-grade Egyptian phosphorit...
