· Unfortunately, most of feldspar resources in China reportedly are characterized with fine liberation size consisting quartz, mica, and iron minerals (Hu et al., 2005, Zhou et al., 2013). Owing to the lack of advanced processing and mechanism to extract feldspar from these minerals, the production of feldspar with high quality is relative low.

Trachytes are extrusive or high-level intermediate igneous rocks, composed dominantly of fine-grained alkali-feldspar usually with phenocrysts of ternary anorthoclase feldspar or of coexisting sanidine and sodic plagioclase. Potassic trachytes ( sanidinites ) occur rarely. With increasing plagioclase, trachytes grade into trachyandesite (latite ...

· A fundamental goal of igneous petrology is to quantify the duration of time required to produce evolved magmas following influx of basalt into the crust. However, in many cases, complex field relations and/or the presence of a long-lived magmatic system make it difficult to assess how basaltic inputs relate to more evolved magmas, therefore, precluding calculation …

· 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 calcium …
