The separation of gold and vanadium in carbonaceous gold ore by one-step roasting method

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. And the effects of experimental parameters such as roasting tempe...
