2021/11/27feldspar - feldspar - Identification of specific feldspars: Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure), which is manifested by parallel lines on certain cleavage surfaces, whereas grains of alkali feldspars do not. This criterion is not, however, absolute;

Silicon recovery from metallurgical

Prior to the experiment, preliminary separation of silicon by manual sorting and gravity concentration was used to increase the silicon content of in the slag. Since the density of silicon is 2.3 g/cm 3 and the density of silicate is 2.5–2.7 g/cm 3 ( Han et al., 2021 ), due to a small density difference, the full separation of silicon and silicate cannot be realized by gravity

Alkali Feldspar

Sanidine (K, Na) (AlSi 3 O 8) is the monoclinic high-temperature alkaline K-Na feldspar, which usually contains about 30%, but sometimes up to 62% sodium (Ab) component. It is found only in young volcanic discharges or volcanic rocks (rhyolite, trachyte, and dacite).

1 1 Define in your own words specific gravity How does this

Higher specific gravity typically means that the concentration of a mineral will be located deeper in the Earth (i.e. continental crust oceanic crust mantle). Specific gravities of 2.5-2.6 seem to favor continental crust, specific gravities of 2.6-2.7 favor the oceanic crust, and specific gravities of 3.2 and higher are most concentrated in the mantle.
