Alkali Feldspar: Mineral information, data and localities.

A subgroup of the Feldspar Group, poor in calcium, and mostly rich in potassium. It is mostly used in petrology for the high temperature series from sanidine to high albite; the series is incomplete at low temperature, but normal albite, orthoclase and microcline are generally still included as alkali feldspars.

Figure 2.1.1 A Part of the Periodic Table Showing the feldspars include aluminum, potassium, sodium and calcium in various combinations. The three main feldspar minerals are orthoclase (a.k.a., potassium feldspar), and two types of plagioclase: albite (sodium only) and

Feldspar

Feldspar is a mineral which gives the ceramic masses a greater sintering with less porosity, a greater mechanical resistance and a reduction of temperature during the firing cycle. When used in ceramic linings, it provides a greater impermeability, a greater surface quality and a greater performance of color development.

Oct 05, 2016Secondary minerals that occur as a result of thermal metamorphism can be used to understand the environment in which they form and evolve. Specifically, phosphate minerals and feldspar can preserve a record of any fluids present, and feldspar microstructures are a sensitive indicator of thermal history.

Application of stage wise flotation using tree technique in Na

Accordingly, a feldspar ore composed of 3.37 % Na 2 O and 3.78 % K 2 O was upgraded to 10.51 % K 2 O and 3.02 % Na 2 O with a K 2 O/Na 2 O = 3.48 in HF medium.
