An alternative mineral in the glass and ceramic industry: Nepheline syenite

In this study, physical and physicochemical experiments were carried out to improve the quality of nepheline syenite ore in Uludag massive, the Bursa Orhaneli region of western Turkey. After determinations of the mineralogical and the chemical characterizations, magnetic separation and flotation methods were applied on the ore sample separately and combined. The best results were found in combination of the high intensity dry magnetic separation and flotation between -200 + 38 μm particle sizes. A nepheline syenite concentrate was obtained with 7.3% K₂O, 5.2% Na₂O, 0.08% Fe ₂O₃ and 0.09% TiO₂ by the weight of 56.6% at the end of the experiments.
