Feldspar minerals: properties, types, uses. Feldspars are the most abundant class of minerals in the Earth's crust.
An improved method for producing high-purity quartz (Qtz) and potassium feldspar (Kfs) concentrates was developed using various chemical reagents. Froth flotation experiments on a Qtz–Kfs mixture showed that quartz could be selectively floated from Kfs in diluted hydrofluoric acid (HF) using a frother. Similarly, feldspar could be selectively …

In the conventional process, HF has been used as pH regulator and activator for feldspar in the operating plants (Gaied and Gallala, 2015, Kangal and Guney, 2002, Sumer and Kaya, 1995). Wang et al. (2018a) reported that until now, only HF can create a large difference in the zeta potential between quartz and feldspars.
Feldspar is the name of a large organization of rock-forming silicate minerals that make up over 50% of Earth's crust. They are discovered in igneous, metamorphic, and sedimentary rocks in all components of the sector. Feldspar minerals have very comparable structures, chemical compositions, and bodily properties.
