  • 11.27 Feldspar Processing

    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 Wikipedia

    Feldspar had been discarded in the process of mining mica until William Dibbell sent a premium quality product to the Ohio company Golding and Sons around 1910. In earth sciences and archaeology, feldspars are used for potassium-argon dating, argon-argon dating, and luminescence dating.

    Aug 10, 2019· This mineral is often called potassium feldspar or K-feldspar because potassium always exceeds sodium in its formula. Potassium feldspar comes in three different crystal structures that depend on the temperature it formed at. Microcline is the stable form below about 400 C. Orthoclase and sanidine are stable above 500 C and 900 C, respectively.

    ChemistryPropertiesAppearanceReactionsFormationSignificanceBenefitsCostUsesProductionResourcesPotassium feldspar falls in the group of aluminosilicate minerals which have a general formula of AT4O8, where A is potassium, T is silicon and aluminum. The silicon to aluminum ratio (Si: Al) ranges from 3:1 to 1:1. K-feldspar contains a group of other minerals that share similar chemical composition but have different physical structures. They include Orthoclase, Sanidine, and Microline. Here are some of the common properties of potassium feldspar:
