Abstract EN
Nepheline syenite ore is an essential constituent in ceramics and glass raw material meals, as a flux and as a source of alumina.
The natural nepheline syenite rocks contain some undesired minerals, which are usually eliminated or reduced to the allowable limits by beneficiation.
The present paper is concerned with characterization and beneficiation of an Egyptian nepheline syenite rock, at Abu Khruq locality, Eastern Desert, Egypt.
The ore is exceptionally hard, with high crushing strength of 875 kg/cm2, and iron oxide content of about 6.5%.
The grain size of the constituents is relatively large.
In some samples, the iron oxides are disseminated within the feldspars and nepheline syenite crystals, or in cracks and fissures within the feldspars crystals.
The rock contains some environmental hazardous elements such as uranium, thorium, and radon.
Magnetic separation and flotation techniques were applied, separately or in combination.
Under optimum operating conditions, magnetic separation followed by reverse anionic flotation gave a concentrate assaying 0.2% Fe2O3 and about 24% Al2O3 at alumina recovery of about 80%.
The radioactive elements were reduced in the concentrate to lower levels than their levels in the original rock.
