Similarly to tremolite asbestos, this type was not commercially used in the U.S. either and would often be encountered as a is primarily found in Finland, but small deposits also occur in North Carolina and Georgia.
The fibers of anthophyllite asbestos can be white, gray or brown and generally develop in large, shapeless bundles. There were only smaller mines in North Carolina and Georgia for this mineral. Anthophyllite asbestos, as it is an insulator and fireproofing agent, is commonly found in flooring.
Anthophyllite asbestos has also been used in cement tiles, body powder and sealant. Most forms of asbestos, including any new asbestos products were banned by the US. The six commercial asbestos minerals (chrysotile, fibrous actinolite, crocidolite, amosite, fibrous tremolite, and fibrous anthophyllite) are classified by the IARC as carcinogenic to humans.
There are currently several lines of research dealing with the inertisation of asbestos minerals among which the dry grinding process has received considerable by: 6. The mining of Anthophyllite started in Finland in Since that time, smaller deposits were mined in Georgia and North Carolina in the USA.
Why Would You Use Anthophyllite. Anthophyllite is a stone of introspection, self-learning, and introspection. Its energies will help you release your self-imposed restraints.

In fact, in decades past, anthophyllite was sometimes an ingredient in talcum powder, a cosmetic product that is used to prevent rashes and chaffing of the skin. Anthophyllite is a common component of some metamorphic and metasomatic rocks.
Its name comes from the Latin word for clove and is an allusion to its typical and distinct clove-brown color. Although it can be differentiated from other amphiboles by its white to brown color, it is often indistinguishable from other amphiboles such as cummingtonite.
It is one of the rarer forms of asbestos. Anthophyllite is found mainly as a contaminant in other minerals, and was not widely used commercially n this country. However, anthophyllite asbestos was mined in North Carolina from about to It is currently used primarily in Finland.
What are Some Common Uses of Anthophyllite Asbestos. Specifically, tremolite asbestos was mined in South Korea , in the Teeter quarry in southeast Pennsylvania, and in the Centreville quarry in north Virginia [9,11] while anthophyllite asbestos.
North Carolina asbestos lawyer Tom Lamb. Amosite, anthophyllite, crocidolite, tremolite, and actinolite are classified as amphiboles. Use of asbestos became popular near the end of the 19th century due to its resistance to heat, electricity, and chemicals and its use continued through the s.

Asbestos is responsible for countless deaths around the world, including at le each year in the U.S. alone. Many Americans might think it’s been banned, but it has not.
It’s lethal, legal and continues to pose serious risks to millions of American families. Asbestos-containing material (ACM) may be present in some older buildings on campus. According to the U.S. Environmental Protection Agency, ACM “that is in good condition and left undisturbed is unlikely to present a health risk.
The risks from asbestos occur when it is damaged or disturbed where asbestos fibers become airborne and can be. The amphibole asbestos, anthophyllite, is associated with asbestos-related disease in humans, along with mesothelioma in animal models.
In humans, however, there are only three cases of histologically proven malignant mesothelioma of the pleura associated with anthophyllite that have been documented in the English-language by: 5.anthophyllite asbestos.
The olivine associated with this asbestos is usually of an inferior quality because of the occurrence of a high percentage of chlorite and talc, developed alongwiththe anthophyllite, which lowersthe magnesiumcontent andrefractoriness.
