A train bringing copper ore out of the mines, Ducktown, Tenn. Fumes from smelting copper for sulfuric acid have destroyed all vegetation and eroded the land (LOC)

    This should have been a clue about enviornmental hazards.

    This area has rehabilitated a bit, but it still looks funky to this day.
  • Red Necks know stuff said:
    This is the caption that Marion Post Walcott included with her photo from 1939 but the actual damage to the vegetation occurred in the late 1800's. The smelting technology of that time did not allow the sulfur dioxide generated by the heating of the ore to be captured. By 1909 the mining companies developed new practices which let them recover the sulfur dioxide and use it in the manufacture of sulfuric acid. Reclamation in the Basin began in the 1930's with varying degrees of success initially. By the 1970's new techniques were developed and today most of the Basin has been revegetated.

    Good to hear that the reclamation effort has been successful. I was there in the 1960s and the sight (in contrast to the lush mountain scenery all around) brought tears to my eyes

    Great scale in this photo. Again, excellent lighting as well.
  • JayneLM, Flickr fickle said:
    The light in this photo is wonderful - it almost looks like a theatre set.
  • John said:
    -And if you look in the lower right hand corner you can see the source of the lighting.

    So SICK!!!
  • Norman Gates said:
    these wires must carry thousands of amperes of current, just like the electric steel smelters.

    I remember when this was quite the operation, and then it all closed rather suddenly, around 1965. Sulphide was a small place, but when the business and people left, it because almost eerily quiet.

White-hot steel pours like water from a 35-ton electric furnace, Allegheny Ludlum Steel[e] Corp., Brackenridge, Pa. The finest quality steels and alloys are produced in these furnaces, which allow much greater control of temperature than other conversion

    www.alleghenyludlum.com/ludlum/pages/contact/Brackenridge... At Brackenridge, four electric arc furnaces melt stainless and other specialty materials for subsequent refining in a 125-ton argon-oxygen decarburization (AOD) vessel which feeds a continuous caster. Slabs and other specialty steel ingots are hot rolled on a six-stand hot strip mill for shipment to other plants. Brackenridge also finishes certain stainless steel, silicon electrical steel and other specialty alloy sheet and strip.

    Wonderful!

    Hi, I'm an admin for a group called Forno: ovens, kilns, furnaces & heaters, and we'd love to have this added to the group!
  • Brant Dempster said:
    Philip Given Good to see Brackenridge going strong again with the new addition.
