Where does aluminum come from? - askaluadmin - 05-08-2018 Aluminium or aluminum is a chemical element with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic and ductile metal in the boron group. By mass, aluminium makes up about 8% of the Earth's crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below. The chief ore of aluminium is bauxite. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. Aluminium is remarkable for its low density and its ability to resist corrosion through the phenomenon of passivation. Aluminium and its alloys are vital to the aerospace industry and important in transportation and building industries, such as building facades and window frames The oxides and sulfates are the most useful compounds of aluminium. Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically, but aluminium is well tolerated by plants and animals.Because of these salts' abundance, the potential for a biological role for them is of continuing interest, and studies continue. RE: Where does aluminum come from? - ircasodle - 05-08-2018 Aluminum is the most abundant metal on earth according to Wikipedia. It is added to fast-food salt, fast-food biscuits, some fast-food pickles, supermarket waffles, many supermarket pizza crusts, quickie-mart salt packets, and numerous other foods. This aluminum is believe to be the aluminum that gets into the brain and interferes with the synaptic chemistry. Many people think aluminum is bad for the health and many people will question why it is added to salt. Some might even consider avoiding it if possible. A good strategy to avoid the dangers of aluminum is to avoid fluoride. Many people feel that the highly reactive (electronegative) fluorine reacts with the aluminum and helps usher it into the brain. Aluminum is generally though of as “positive charged” element and is given an oxidation state of +3,+2, or +1. There is a lot of information on how fluoride doesn’t actually remineralize the teeth but just “kills” bacteria in the mouth that make lactic acid from 6-carbon sugar. Many people now are switching to toothpaste with Xylitol, a 5-carbon sugar. This avoids the dangers of fluorine which are known. Many people challenge the research indicating reduced intelligence and damage to other bodily tissues from fluorine (in water and absorbed through the gums). As a culture, we are still probably a few years away from changing. For example, Lead is known to be highly toxic and neurologically destructive yet piston-engine aircraft still burn leaded-gasoline and there are lower intelligence levels around municipal airports. The EPA and FAA are both pointing the finger at each other while we wait on specific approvals (Supplemental Type Certifications aka STC’s) of lead-free Aviation Gasoline (“AVGAS”) for each engine type.
