Feldspar Properties, Uses, Types, & Facts Britannica
feldspar, any of a group of aluminosilicate minerals that contain calcium, sodium, or potassium. Feldspars make up more than half of Earth’s crust, and professional literature about them constitutes a large Most feldspar minerals have a Mohs hardness of approximately 6 to 6.5 and a specific gravity between 2.5 and 2.8. They all have a vitreous luster that is often pearly on cleavage faces. The accompanying table shows Feldspar minerals make up over 50% of Earth's crust.

9.3.1: Magmatic Ore Deposits Geosciences LibreTexts
9.3.1.1 Magmatic Sulfides and Cumulates. Mafic and ultramafic magmas, like all common magmas, contain the major elements oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. But they typically also contain other elements including sulfur, nickel, and less common metals such as platinum, palladium, and chromium.In feldspar processing, flotation beneficiation tailings that containing high ratio of titanium minerals emerge at a considerable amount as a result of beneficiation of feldspar reserves with high TiO2 content due to required specifications by global feldspar market. Recovery of titanium minerals from these tailings which can be evaluated as Investigation of recovery possibilities of rutile minerals from the
