Nepheline syenite is a complex rock consisting of different mineral phases such as nepheline alkali feldspar and biotite It is a promising source for the recovery of potassium and alumina values
Nepheline syenite contains the mineral nepheline instead of a part of the feldspar of ordinary syenite It may carry corundum and sodalite as it does near Bancroft Eastern Ontario Diorite Diorite is composed of hornblende and feldspar the hornblende in equal amount or in greater quantity than the feldspar so that the rock is dark
Feldspar is also used as a filler in paint rubber and plastics The raw materials most often substituted for feldspar in a number of end uses are aplite and nepheline syenite Aplite which contains plagioclase lime soda feldspar is mined in Virginia and used mostly in glassmaking
The article presents information on the market for feldspar and nepheline syenite in the U S In 2006 U S feldspar output sold or used was an estimated 760 kt or 43 million free on board plant The estimated end use distribution of domestic feldspar in 2006 was glass and pottery Imports of feldspar in the U S in 2006 amounted to about 5 kt
Nepheline Syenite makes glass batches to have lower viscosity and easier workability compared with Potash Feldspar Its high alumina and alkalis content also makes it so suitable for the glass manufacturing Compare with Feldspar the advantages of Nepheline Syenite are listed as follows 1
14 beneficiating plants and 1 grinding plant 3 of which produce potash feldspar the remainder of which produce soda mixed feldspar or feldspathic sand mixtures North Carolina has six plants California has sodium potassium feldspars and nepheline with little or no free quartz All of the nepheline syenite used in the United States is

11 27 Feldspar Processing 11 27 1 General1 Feldspar consists essentially of aluminum silicates combined with varying percentages of potassium sodium and calcium and it is the most abundant mineral of the igneous rocks The two types of feldspar are soda feldspar 7 percent or higher Na O and potash feldspar 8 percent or higher K O
Feldspar can be replaced by other minerals and mineral mixtures of similar physical properties Minerals that could be used to replace feldspar include pyrophyllite clays talc and feldspar silica quartz mixtures The abundance of feldspar will make these substitutions unnecessary for
Comparison of silicate minerals as sources of potassium for plant nutrition in sandy soil such as feldspar and nepheline occur widely as potential sources of K for use in soils where these
experimental determination of mineral dissolution rates indicate that nepheline dissolves 100 times more quickly than potassium feldspar and this suggests that nepheline bearing rocks are more effective as sources of K for plant growth than granitic rocks even though these have higher K contents
