Bad Effects Of Gold Extraction Plant

  • Rcovery of gold in pyritic ores - Mine

    This would make the recovery of gold from pyritic sulfides economical, and negate spending hundreds of millions of dollars on roasting plants. But in the end, it all comes down to cost, which would be the most cost effective. We know roasting is almost prohibitively expensive, so I would think that treating in a heap leach, prior to cyanidation, would be much more cost effective.
