Nepheline syenite - Wikipedia

Nepheline syenite is a holocrystalline plutonic rock that consists largely of nepheline and alkali feldspar. The rocks are mostly pale colored, grey or pink, and in general appearance they are not unlike granites, but dark green varieties are also known. Phonolite is the fine-grained extrusive equivalent.

Nepheline Syenite - an overview | ScienceDirect Topics

Wall and floor tiles: The most studied zeolites application is the substitution of conventional fluxes in sintered ceramic tiles.In fact, the main drawback correlated to the use of these materials—mainly potassic and sodic feldspars, but also nepheline syenite, talc, glasses, and glass-ceramic frits—is their high cost of supply and processing (milling and firing).

Nepheline Syenite - Anglo Pacific Minerals

Nepheline syenite is a composed of three primary minerals: the albite form (sodium) of feldspar, the microcline form (potassium) of feldspar and nepheline (feldspathoid). The existence of nepheline and the absence of crystalline silica is what sets this uniquely occurring rock apart from feldspar fillers, which contain just albite and microcline.

Hydrothermal beneficiation of Egyptian nepheline syenite ...

Jan 01, 1993 · Egyptian nepheline syenite was chemically beneficiated in an autoclave at temperatures ranging from 150 to 250°C using sodium hydroxide solution containing 155–388 g Na 2 O/l. The factors affecting the leaching process were studied from the concentrations of SiO 2 and Al 2 O 3 determined in the solution and concentrate. Under the optimum conditions a concentrate with 27% Al 2 O 3 and 44% ...

DRY MAGNETIC SEPARATION OF NEPHELINE SYENITE ORES

(Bolger 1995, Harben 1995). Since it would be most unusual to find a nepheline syenite ore that could be used commercially for glass and ceramics purposes without beneficiation, and due to the arid nature of the Egyptian ore deposits, it is important to study the amenability of this ore to dry beneficiation. Nevertheless, the dry processing
