feldspars use mining

Ch 4

because feldspars form at high temperatures they are unstable at Earth's surface where lower temperatures and pressures + interactions in earth's systems cause minerals to change into more stable variations. these changes are called chemical and physical weathering. chemical weathering of feldspars can be done by hydrolysis and dissolution.

Orthoclase: The mineral Orthoclase information and pictures

Orthoclase is one of the most common minerals, and occurs in numerous mineral environments. It is polymorphous with the minerals Microcline and Sanidine. These three minerals form the Potassium Feldspar group. They are almost identical in physical properties, and it is sometimes impossible to distinguish one another without x-ray analysis.

Feldspar

The structure of feldspars is a three-dimensional framework of linked SiO 4 and AlO 4 tetrahedra, with sufficient opening in the framework to accommodate K, Na, Ca, or Ba to maintain electroneutrality. In the building up of the framework, four-membered rings of tetrahedra are the basic units.

How Is Quartz Mined?

Full Answer. Mined quartz is intended for commercial use in both jewelry and electronics and must therefore undergo an extensive cleansing process, which strips the minerals of all chemical impurities and physical flaws.

Flotation separation of Na

Abstract. A major proportion of feldspar ores contain both Na-feldspar (Albite) and K-feldspar (microcline or orthoclase) in the same matrix, usually in quantities of about 3–5% Na 2 O and K 2 O. Despite their identical crystal structures and physicochemical properties, flotation appears to be the only plausible method of separating these minerals.
