A mineral is a naturally occurring chemical compound usually of crystalline form and not produced by life processes. A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids. The study of minerals is called mineralogy. To meet the definition of “mineral” used by most geologists, a substance must meet five requirements:

Nepheline

Nepheline is the most common feldspathoid mineral in the world, its name from the Greek word nephele, which means “cloud” a reference to the fact that the mineral becomes cloudy or milky in strong acids. Specimens are usually white in color, often with a yellowish or grayish tint.

Zeolites

Zeolite is a group of silicate minerals that a family of hydrated aluminosilicate minerals that contain alkali and alkaline-earth metals with unusual properties with importance industrial application. Zeolite form is usually well-formed crystals with pale colors and generally soft and can easily crushed.They are found in geologically young volcanic fields.

Natrolite

Natrolite is a tectosilicate mineral belong to zeolite group members.Its formula Na2Al2Si3O10 • 2H2O. A hydrated sodium aluminosilicate, natrolite takes its name from the Greek word natrium, which means “soda” a reference to the sodium content of this mineral. Natrolite can be pale pink, colorless, white, red, gray, yellow, or green.

Magnesio-hornblende

Hornblende

Hornblende is a inosilicate amphibole minerals, which are two type hornblende minerals. They are ferrohornblende and magnesiohornblende. They are an isomorphous mixture of three molecules; a calcium-iron-magnesium silicate, an aluminium-iron-magnesium silicate, and an iron-magnesium silicate.

Arsenic

Arsenic is a native element with the formula As and atomic number 33. Known since antiquity, arsenic is widely distributed in nature, although it is unusual in native form. It is classified as a semimetal, because it possesses some properties of metals and some of nonmetals. Crystals are rare, but when found they are rhombohedral.

Sulfur

Sulfur is the tenth most common element by mass in the universe, and the fifth most common on Earth. It (also spelled sulphur) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Under normal conditions, atoms form cyclic octatomic molecules with a chemical formula S8.
