It is the other main source of gold in New Zealand and has produced a lot of our gold. Gold is often found in quartz reefs in the ground. So gold ore mining often leads a miner underground, or alternative requires large holes dug to access the gold from the

  • How Is Gold Processed? , Reference

    Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.Gold Processing Methods & Gold Ore Extraction,Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration.
