The pyrite gold ore has fine particles and contains harmful elements such as arsenic.The gold recovery rate is only 51%to 63%when the roasting+cyanidation process is employed,and high-value iron concentrate cannot be obtained.The physical and chemical properties of the pyrite gold ore are analyzed,and its roasting is simulated to obtain the best roasting effect and control parameters.According to the findings of the roasting test,the fluid-ized bed furnace is optimized and retrofitted to improve the roasting effect and gold leaching rate,and obtain iron products with low arsenic content,there-by realizing the efficient utilization of difficult-to-treat pyrite resources.
