Gold Ore Roasting Plant - Mineral Processing & Metallurgy

Fluidized bed roasting was selected because it efficiently destroys the sulfide minerals and organic carbon components of the ore while maintaining excellent control of the process temperatures. Temperature control in the roaster is critical because there is a substantial decrease in gold extraction at temperatures above 1050°F, and also coal ...
