DescriptionRelation to MiningUsesFeldspar is the name given to a group of minerals distinguished by the presence of alumina and silica (SiO2) in their chemistry. This group includes aluminum silicates of soda, potassium, or lime. It is the single most abundant mineral group on Earth. They account for an estimated 60% of exposed rocks, as well as soils, clays, and other unconsolidated sediments, and are principal components in rock classification schemes在mineralseducationcoalition上查看更多信息

Feldspar iMinerals Inc.
Feldspar’s physical properties of dispersibility, weatherability, scrub resistance, and mildew resistance make it attractive to the coatings industry. I-Minerals is focusing on potassium feldspar (K-spar). Deposits of high-quality K-spar that can be economically extracted are rare.

The feldspar provides alumina, which improves durability of the glass. The feldspar-rich rock is extracted using open pit methods, then crushed, classified and dried on-site. Heavy minerals are removed from the material by electrostatic and magnetic processes. The processed material is then transported by truck and rail to markets.

How Is Quartz Extracted? Sciencing
Quartz is extracted from open pit mines. Miners only use explosives on rare occasions when they need to expose a deep seam of quartz. The reason for this is that although quartz is known for its hardness, it damages easily if it is suddenly exposed to a change in temperature, such as that caused by a blast.

The presence of feldspar lamellae in another feldspar gives rise to the Schiller effect, an iridescence due to light refraction. Schiller is best developed in labradorites, creating a lovely color play in shades of green, blue, gold and yellow. The color may be uniform or vary within a single feldspar crystal.
