World is running out of tungsten?
OK, Iggy, can you come somewhat close to the $35/kilo Richard
mentioned? I wonder what shipping would cost, but then my neighbor has a shipping broker I might be able to tap into.

Not really, you can just sell it to me. i |

Thanks, Richard. Where did you get your figures? I've been looking for
quite a while and can't find squat online when it comes to tungsten. That makes me rather at the mercy of the few dealers around here who will even take it.

A friend photographed his aerial view flying over a long ago closed copper mining operation in NM.. the vast scale of those mines can't be appreciated by looking at pictures in textbooks. Check Norilsk in Siberia/Russia. It's similar latitude to Alaskan North Slope, but it's an industrial city with population of 100,000 and a mile- wide, half-mile deep hole in the ground, whereas people commute to the Slope oilfields by flying in and out. Norilsk also apparently holds the record for most polluted city in the world. Russians are tough people. |

Environment Landscape near Norilsk Much of the surrounding areas are naturally treeless tundra. Pollution The nickel ore is smelted on site at Norilsk. The smelting is directly responsible for severe pollution, generally acid rain and smog. By some estimates, 1 percent of the entire global emissions of sulfur dioxide comes from this one city. Heavy metal pollution near Norilsk is so severe that mining the surface soil is now economically feasible, as a result of acquiring high concentrations of platinum and palladium through pollution.[11] The Blacksmith Institute[8] included Norilsk in its 2007 list of the ten most polluted places on Earth. The list cites air pollution by particulates (including radioisotopes strontium-90, and caesium-137 and metals nickel, copper, cobalt, lead, and selenium) and by gases (such as nitrogen and carbon oxides, sulfur dioxide, phenols, and hydrogen sulfide). The Institute estimates four million tons of cadmium, copper, lead, nickel, arsenic, selenium, and zinc are released into the air every year.[citation needed] According to an April 2007 BBC News report,[12] the company accepted responsibility for what had happened to the forests, and insisted they were taking action to cut the pollution. For the period up to 2015–2020 the company expects to reduce sulfur dioxide emissions by approximately two-thirds, but admits it is hard to guarantee this pace of reduction because they are still developing the technology. CNN has claimed that there is not a single living tree within 48 km (30 mi) of the nickel smelter Nadezhda ("The Hope").[13] -- Knowledge speaks, but wisdom listens. -- Jimi Hendrix |
