Taking the gold concentrate containing arsenic in Hunan province as raw material, the mineral was roasted by microwave radiation to study the variation rule of arsenic and sulfur content in gold concentrate with temperature, power, holding time and other parameters, and the reaction mechanism of gold concentrate in microwave field heating was obtained by detecting and analyzing the products in the reaction process.
