  • Types of Porphyritic Rocks

     · — This name refers to the structure, which is formed of larger crystals set in a finegrained or glassy groundmass. The porphyritic structure may be plainly visible, the larger crystals being easily seen (phenocrysts), or it may require the microscope to bring it out. Porphyritic structure may appear in any igneous rock, but the true porphyries are rocks in which there is a marked contrast ...

  • Ultrafine nepheline syenite

    These mechanical properties involve use of a fine grain particulate form of nepheline syenite which is abrasive. Consequently, the granular nepheline syenite has a tendency to abrade and erode rapidly equipment used in processing. It has been determined that by reducing the particle size of any organic oxide material, such as nepheline syenite, the abrasive properties of the material are ...

     · Nepheline Syenite Nepheline syenite is composed essentially of nepheline (NaAISiO4), albite, and microcline [7]. The ore contains up to 15% alkalis and at least several percent iron oxide. In addition, tailings from the nepheline beneficiation process contain iron oxide levels approaching 10%. Thus, in spite of the presence of a glass former (SiO2), nepheline ore, or nepheline tailings, might ...

     · Pseudoleucite syenite is a magmatic rock, which is rarely found in the foidolite rock group. With respect to the compositions of similar alkali feldspars as sodium potassium aluminosilies, feldspathoid minerals are normally characterized by silica deficiency. Pseudoleucite syenite formed from alkaline (sodium and potassium)rich and silicapoor magmas.
