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 Author: Abdel-Zaher M. Abouzeid, Abdel-Tawab A. Negm. Nepheline in C anada: There is a large deposit of Nepheline Syenite in Canada close to Havelock, Ontario. This deposit encompasses 3, acres of land and is actively mined by the company Unimin Canada Limited. This company is Canada sole Nepheline provider.
Nepheline Syenite is an anhydrous sodium potassium alumino silicate. Although feldspar-like in its chemistry, mineralogically it is an igneous rock combination of nepheline, microcline, albite and minor minerals like mica, hornblende and magnetite. It is found in .

Report an Error. 3M™ Industrial Grade nepheline syenite is a versatile mineral used in a variety of industries, primarily as a silica-free fluxing agent in ceramics and glass manufacturing.
It lowers the overall melting point of the clay body while maintaining structural porcelain integrity to the highest moisture resistance standards. Nepheline crystals are rare and belong to the hexagonal system, usually having the form of a short, six-sided prism terminated by the basal unsymmetrical etched figures produced artificially on the prism faces indicate, however, that the crystals are hemimorphic and tetartohedral, the only element of symmetry being a polar hexad ry: Tectosilicate, feldspathoid.

Publication Number: AR69 pt8 Date: Author: D.F. Hewitt. Europe is the largest market for feldspar and nepheline syenite followed by Asia Pacific and North America.
Italy, Spain, United Kingdom, Germany, and France are the major consumers of feldspar and nepheline syenite in research report analyzes this market on the basis of its market segments, major geographies, and current market trends. Nepheline syenite is a quartz-free aluminium silicate consisting primarily of the minerals nepheline, microcline and albite.
Because of its extremely low melting point and high alumina content, nepheline syenite is used as a glass phase promoter, a ceramic flux and also as a functional filler in paint, plastics & more. The Goulding–Keene nepheline pegmatite near Bancroft, Ontario.
Guide Book, Geology of parts of eastern Ontario and western Quebec. Nepheline syenite deposits of southern On-tario. A speculative working-hypothesis is offered to account for the genesis of the well-known nepheline- and corundum-bearing gneisses of southeastern Ontario.
Field evidence appears to indicate that most of the nepheline and corundum rocks of this area were derived from pre-existing dark gneisses of the Grenville series, by reaction with Cited by: Nepheline Syenite.
Nepheline syenite is a white to light grey medium-grained igneous rock. It consists mostly of soda feldspar, nepheline and potash feldspar, accessory magnesium and iron-rich minerals.
The Canadian nepheline syenite industry began in when claims were staked on Blue Mountain near Peterborough, Ontario, where it is still.
Mountain and Nephton nepheline syenite deposits in Ontario. These deposits are within a Precambrian nepheline intrusion about 9 km long and up to km wide. Nepheline syenite in Norway comes from Stjernøy Island, km north of the Arctic Circle, where the syenite occurs in dykes and stocks.

Where Al 2 O 3 in nepheline syenite is more than 20%, Na 2 O and K 2 O are less than 10% and SiO 2 does not exceed 55%, nepheline syenite can be processed by sintering to produce alumina, Portland cement and other.

Abstract. Nepheline natrolite syenites of Center 2 of the Coldwell alkaline complex exhibit rare wispy mafic-rich modal layering, extensive xenolith-rich zones and a wide variety of textural types, the latter resulting from the imposition of high temperature shearing and recrystallization on consolidated by: In addition to the USSR, nepheline-syenite deposits are also found in the vicinity of Oslo, Norway, and in southern Greenland, in Canada, in southern Africa, and on Madagascar.
Nepheline syenites occur in association with apatites (Kola Peninsula), graphite (Saian Mountains), cryolite (Greenland), and a number of rare elements.About million years ago, there was a period of mountain building which affected all of eastern Ontario.
The igneous and sedimentary rocks of the area were highly folded, compressed and metamorphosed. They were intruded by magmatic rocks ranging in composition from gabbro and granite to syenite and Nepheline syenite.
