Feldspar Gem Guide and Properties Chart

Feldspar minerals are some of the most abundant minerals within the Earth's crust and are a common component of rocks. Species that are rich in potassium (K) are called potassium feldspars. Orthoclase, Microcline (Amazonite), and Sanidine are potassium feldspars. Feldspars rich in sodium (Na) or calcium (Ca) are plagioclase feldspars.

Mechanism of separating muscovite and quartz by flotation

Flotation experiments were performed to investigate the separation of muscovite and quartz in the presence of dodecylamine (DDA), tallow amine (TTA) and dodecyltrimethylammonium bromide (DTAC). The adsorption mechanisms of these three kinds of amines on muscovite and quartz were studied by FT-IR spectrum analysis, …
