Albite (NaAlSi 3 O 8) is a main rock-forming mineral and ubiquitously exist in soil and rock fracture fillings as a product of advanced weathering processes. The basic structure of albite is a tetrahedron, which is composed of alumina tetrahedra and silicon tetrahedra, with the silicon tetrahedra sharing a plane of oxygen atoms .

The primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. The location and shape of the deposit, strength of the rock, ore grade, …

A mineral is a naturally occurring solid with a welldefined chemical composition and a definite atomic structure that has been formed by geological processes. contains the minerals quartz, orthoclase, and albite) or a single mineral (, tungsten, aluminum, and zinc, all of which are extracted from mined

Lepidolite is a lithium-rich mica known for its pink and lilac colors. It is a common matrix mineral to Tourmaline and Quartz, providing them with a very aesthetic and glittery base. A pink variety of the related mica mineral Muscovite can be identical in appearance to Lepidolite, and is many times incorrectly labeled as Lepidolite.

Hydrothermal alteration is important in mineral exploration and mining because it can provide valuable information about the location and type of minerals present in an area. By understanding the geological processes that led to the formation of mineral deposits, geologists and miners can better target areas for exploration and extraction.
