Plant Labels - from used aluminium cans
Gold can be toxic to the liver and kidneys. Perhaps a prudent person
should stop wearing man-made gold while avoiding aluminum. Don It's compounds are, but gold worn as jewelry or eaten on desserts or drunk in liquor are for the most part inert and not readily absorbed by the body therefore not a concern. Cheers, Ned |

news In article , "Don K" wrote: Man-made aluminum & aluminates MIGHT have some involvement in the development of alzheimers disease, though years back when Science Digest did a whole issue about it, looked like only about one out of ten researchers thought it much likely. Aluminum is an element and strictly speaking, is not something that is man-made. Pure aluminum does not exist in nature, & its existence was not even known until 1808, & it was another 80 years before it could be extracted affordably from boxite & alumina. Boxite is found just about everywhere in nature; aluminum per se is not. When metalurgists first learned to purify aluminum from boxite, it cost more per ounce than gold. Nowadays it costs us here in the Northwest our salmon resources, there being no more salmon runs at all in rivers & streams near aluminum plants. Most mining involves dealing with nasty by-products. A lot of gold is also obtained by refining ore thru all sorts of chemical processes. Yet we don't refer to it as man-made gold. There's no alchemy involved. It's just recovering the gold that is locked up in other compounds. Gold can be toxic to the liver and kidneys. Perhaps a prudent person should stop wearing man-made gold while avoiding aluminum.

There are no such things as gold ores to my knowledge.
Sure there is, Calaverite, Chalcocite, Bornite, Chalcopyrite and enargite, are a few.... Gold is an almost inert element. As far as I know, gold is always found as a simple metal. No. That would be native gold--which is rare. Most gold is in ores. Cheers, Ned |
