 — Mica minerals can be removed in an amine collector system with a slurry pH of 2.5-3.5; For silicate minerals, when the pH of the pulp is 3-4, a sulfonate collector can be used to separate them to the surface.

 — Feldspar muscovitisation reactions play an important role in deformation processes (e.g. White and Knipe, 1978, Knipe and Wintsch, 1985). The most noted way is by reaction-enhanced ductility (White and Knipe, 1978), where relatively strong feldspars [at temperatures less than, say, 500°C (e.g. Voll, 1976, Tullis, 1983 and many others)] are …

Typical of this is the separation of mica from quartz and feldspar (Browning, 1973). Mica and feldspar are close to each other in respect to their density. The densities of feldspar and mica minerals are approximately 2.65 and 2.7-3.4 g/cm3, respectively (Ipekoglu and Asmatulu, 1996).

Feldspars are also significant components of the Precambrian sandstones that filled the Mid-Continent Rift valleys, such as the Hinckley and Fond du Lac Sandstones. Potassium Feldspar Gallery Commonly confused with... A combination of hardness, non-metallic luster and two good cleavage directions at right angles to one another serves to ...

In the present study, effects of several operating parameters on the separation efficiency of mica from feldspar by spiral concentrator were investigated. For this purpose, an albite ore containing mica was treated in a full scale Reichert …

 — In this paper, a complete scheme aimed at improving the flotation performance of spodumene and comprehensively recycling mica and feldspar from lithium tailings in an economical and ...

 — Feldspar - Mineralogy, Crystallography, Structure: Sanidine and orthoclase are monoclinic or nearly so; the plagioclase feldspars are triclinic.
