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 …
Albite belongs to the Plagioclase Feldspar group, an isomorphous solid solution series.Albite is one end member, containing sodium and no calcium. The other end member, Anorthite, contains calcium and no sodium.The intermediary members are Oligoclase, Andesine, Labradorite, and Bytownite.Oligoclase and Andesine are considered by some to be a variety of Albite rather then a separate mineral.

Several methods used to separate the feldspar from the quartz and to remove certain undesirable minerals (fluorite and topaz, iron minerals, and metal sulfides). Two methods were successful for removing the bulk fluorine (fluorite and topaz) and metal sulfides prior to the separation of the quartz and feldspar products by feldspar flotation.

Quartz is physically and chemically resistant to weathering. When quartz-bearing rocks become weathered and eroded, the grains of resistant quartz are concentrated in the soil, in rivers, and on beaches. The white sands typically found in river beds and on beaches are usually composed mainly of quartz, with some white or pink feldspar as well.

What is common to all the feldspars is the same arrangement of atoms, a framework arrangement, and one basic chemical recipe, a silicate (silicon plus oxygen) recipe. Quartz is another framework silicate, consisting only of oxygen and silicon, but feldspar has various other metals partly replacing the silicon.
Quartz is also the most varied of all minerals, occurring in all different forms, habits, and colors. There are more variety names given to Quartz than any other mineral. Although the Feldspars as a group are more prevalent than Quartz, as an individual mineral Quartz is the most common mineral.

What is Plagioclase? "Plagioclase" is the name of a group of feldspar minerals that form a solid solution series ranging from pure albite, Na(AlSi 3 O 8), to pure anorthite, Ca(Al 2 Si 2 O 8).Minerals in this series are a homogenous mixture of albite and anorthite. The names of the minerals in the series are arbitrarily given based upon their relative abundance of albite and anorthite.
Feldspar. Feldspar comprises a group of minerals containing Potassium, Sodium, Calcium and Aluminium Silicates and constitutes most common and very important group of rock forming minerals. Most commercial Feldspars occur in Pegmatites associated with one or more accessory minerals like Quartz, Mica, Garnet, Tourmaline and Kaolinite.
