Fabrication of Arsenic Sulfide using Thermal Treatment


To remove the arsenic from gold concentrate using a thermal decomposition method, a test was conducted while changing the reaction time at 700°C. Additionally, the volatile arsenic from the gold concentrate was recovered using a bag-filter. The arsenic content in the concentrate was rapidly reduced from 12.62wt.% to 1.40wt.% after 1-hour burning and to below 1wt.% after 2 hours, indicating approximate 95% removal rate.
