This paper describes a novel hydrothermal method for preparing potassium sulfate and zeolite NaA from K-feldspar ore. The 3-step process involves the hydrothermal decomposition of K-feldspar, the preparation of potassium sulfate from kalsilite, and the synthesis of zeolite NaA from alumina-silica residue.
Alkali feldspars constitute a solid-solution between K-feldspar or orthoclase molecule (Or) and albite (Ab), which represents also the sodic end-member of the plagioclase series. Anorthite (Ca[Al 2 Si 2 O 8]; An) is present in small quantities in alkali feldspars, usually constituting less than 5% of the solid solution and predominantly found in Na-rich alkali …

Cutting, crushing or grinding aggregates, hardened cement, concrete or other crystalline silica-bearing materials will release respirable crystalline silica. Use all appropriate measures of dust
Calcium feldspars are not common and never near theoretical. Thus even if the CaO does not predominate over the K 2 O and Na 2 O it may still be labeled a Ca-Feldspar if there is an appreciable amount.
Feldspar is an aluminosilicate mineral containing calcium, sodium, and potassium.

To recover potassium from feldspar, a biowaste, i.e., eggshell, was used. The chief composition of eggshells is calcite. As it is a rich source of Ca, hence it is used with HCl to produce calcium chloride. Feldspar is an aluminosilicate mineral that bears potassium in the interstitial sites. To unlock the potassium from the interstitial sites, it was roasted with …
Feldspar and feldspar raw materials are products of extraction with high contents of feldspar minerals. Feldspars in rocks consist of a mixture of feldspar minerals, which are divided into three basic groups. These are calcium feldspar (labeled Ca), sodium feldspar (Na), and potassium feldspar (K).
Feldspar . Feldspars are aluminosilicate minerals with varying amounts of potassium, sodium and calcium in a solid solution series. It is the most abundant mineral group, constituting ~60% of the Earth's crust. ... In addition to this, ~50 000 t/year of a quartz–feldspar blend are produced for use in glassmaking by crushing granite near ...

The first and most significant type is the plagioclase feldspars, which can occur in nearly every igneous and metamorphic rock as a rock forming mineral. The plagioclases are represented by a binary solid solution series with sodium (albite or albitic) and calcium (anorthite or anorthitic) endmembers.
