Production, Reserves, and Processing of Feldspar and …

feldspathoid rocks are extracted as feldspar substitutes [20]. Feldspathoids (foids) are rock-forming minerals similar to feldspar but with smaller amounts of silica [1,21] (Table 1). They can be used for glassmaking, ceramics [22–24], fillers, and possibly as sources of potassium for fertilizers [25] in the same way as feldspar. Table 1.Web

Jindera Granite where a small feldspar quarry operated prior to 1949. The rock is very coarse-grained, with aplite dykes and minor pegmatite. The rock contains 70–75% feldspar, 15–25% quartz, 5–10% muscovite and up to 3% biotite. The average total iron (FeO+Fe2O3) and alkali (K2O+Na2O) contents of the granite are 1.57% and 9.1%, respectively.Web

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 …Web
