  • Gold Ore Roasting Plant - Mineral Processing Metallurgy

    The two stage design is preferred because; 1) the single stage design results in significant levels of unoxidized carbon exiting the roaster, reducing gold recoveries and 2) the two stage design allows the most efficient utilization of oxygen. The roaster is operated with the gas flow countercurrent to the solids flow.
