Amount Of Cynide For Heap Leaching Pad Tailing

  • 「cyanide extraction of gold mining results」

    cyanide's efficiency makes mining more wasteful. because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold.
