The name feldspar encompasses a wide range of related minerals. Collectively, they are the most abundant group of minerals in the world, forming about 60 percent of the earth's crust. Feldspars are particularly abundant in igneous rocks like granite. Most often, commercial feldspar is mined from pegmatite or feldspathic sand deposits.

The saltation fluxes from the feldspar-quartz sand also remained relatively stable throughout the experiment with flux around 2.5 × 10 −3 kg m −1 s −1 (Figure 3) and in accordance with previous wind tunnel and in situ experiments on feldspar-quartz sand (see Table 1 in Martin & Kok, 2018; Swet et al., 2019, respectively).
Use of quartz and quartz-feldspar sands for iron casting molds and rods is studied. A requirement is substantiated for their use as molding materials for preparing iron castings weighing up to 1500 kg and the casings of drying cylinders weighing up to 36 tons. It is concluded that it is preferable to use Gusarov, Karelian, and Finnish sands over other quartz sands. …
