Vermiculite is a natural, inorganic, non-toxic mineral that expands under high temperature. It is a relatively rare mineral, belonging to the silicate group. Its crystal structure is monoclinic crystal system, and its appearance is similar to mica.

Non-toxic. Medical stone is a compound mineral or medicinal rock that is non-toxic and harmless to organisms and has certain biological activity. The main chemical composition of medical stone is inorganic silicaluminate. Including SiO2, Al2O3, Fe2O3, FeO, MgO, CaO, K2O, Na2O, TiO2, P2O5, MnO, etc., also contains some of the major elements required by animals, such as: K, Na, Ca, Mg, Cu, Mo and other trace elements and rare earth elements, about 58 kinds of.

Coral sand is a fragment of coral or shell that consistently releases calcium carbonate and comes in a variety of sizes and sizes. The biggest feature of coral sand is that it is rich in micropores, suitable for the survival of a large number of biochemical bacteria, and can be used as a filter material.

The main oxides of fly ash in China's thermal power plants are SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2 and so on. With the development of electric power industry, the discharge of fly ash from coal-fired power plants is increasing year by year, and it has become one of the industrial wastes with large displacement in China. If a large amount of fly ash is not treated, it will produce dust and pollute the atmosphere. If discharged into the water system, it will cause the silting of the river, and the toxic chemicals in it will also cause harm to human and biological. But fly ash can be used as resources, such as as an admixture of concrete.

Washed stone is a decorative material made of natural stone, through a special treatment process, so that the fine particles on the surface of the stone are removed, exposing the natural texture and color of the stone. This treatment can highlight the texture and beauty of the stone, while increasing its durability and anti-slip properties.

Colored sand is divided into natural colored sand, sintered colored sand, temporary dyed color sand, permanent dyed color sand. Its characteristics are: bright color, acid and alkali resistance, ultraviolet resistance, do not fade. Natural color sand: It is crushed by natural ore, which does not fade but has more impurities. Temporary dyeing color sand: bright color, easy to decolorize.

Medical stone is a kind of natural ore with porous, light weight and high temperature resistance. It is widely used in the fields of building materials, agriculture, horticulture, fireproof materials and industrial filtration, and plays an important role.

Geophagy has been considered as an adaptive behavior in humans and animals (1) and the clays have been considered the healing materials from ancient times. As geophagia is an occasionally habits of animals and humans (babies and pregnant women), physiologically it is assumed that earth might have some beneficial effects on body function. Bentonite is absorbent aluminium phyllosilicate clay. It is named after Fort Benton, Wyoming where its largest sources are found. Its other name, Montmorillonite clay, stems from the region of France called Montmorillon, where it was first found. It has been used and eaten from ancient time till now as human believes in its therapeutic benefits. When it is mixed with water a paste is formed which has been used both externally and internally. In some places such as Iran, it has been widely used as a hair cleanser from old time. There is enough literature showing its safety after chronic oral consumption (2–6). As this clay is abundant, non-expensive and natural, this article aimed to review the scientific papers reporting the effects of this clay on body.

Vermiculite is a natural, inorganic, non-toxic mineral that expands under high temperature. It is a relatively rare mineral, belonging to the silicate group. Its crystal structure is monoclinic crystal system, and its appearance is similar to mica. Vermiculite is produced by the hydration of certain granite.

In 2014 a researcher noticed some unusual spots on the rock of a volcanic outcrop in Western Australia. Under a microscope the spots were identified as a brand-new mineral, eventually named putnisite. Headlines celebrated the discovery’s unique chemical properties and translucent, purple crystalized structure. Every detail of its composition was catalogued among a long list of the world’s known minerals.

Made from ethically-sourced minerals like mica, zinc oxide, and titanium dioxide, mineral makeup has many more benefits for your skin than regular makeup. Suitable for sensitive complexions, discover the key benefits of mineral foundation that might help you make the switch.
