Separation Method For Gold

The separation of gold and vanadium in the refractory carbonaceous gold ore had been performed by one-step roasting method.The thermodynamic viability of the possible reactions in the process was analyzed based on thermodynamic data.

What Is Gold Extraction With Pictures Wisegeek

This method of gold extraction, also known as gold cyanidation, takes several months.Dump leaching is used to extract mostly lower quality gold and metals.It does not require the rock to be broken into small pieces and is cheaper and less effective.In some cases, gold cannot be removed by cyanidation alone.
