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).

Feldspathic Sand is a direct ship silica-potassium feldspar product. The sand is screened tailings that were generated from historic kaolin mining. As required, the sand is screened during loading to -1/8 th inch to remove organics and finer material less than one eighth of an inch. The feldspathic sand is the first commercially available

Feldspar Imerys

Feldspar minerals are essential components in igneous, metamorphic and sedimentary rocks, to such an extent that the classification of a number of rocks is based on their feldspar content. Although highly present in igneous rocks like granite, commercial feldspar is generally mined from pegmatite or feldspathic sand deposits.
