Refractory gold ore resources have become the main source of raw materials for China's gold industry production,in order to improve the recovery rate of gold from refractory gold ores,pre-treatment is generally required before cyanide leaching.This paper explores the main treatment processes for extracting gold from refractory gold ores,with a focus on analyzing the roasting oxidation process.During this process,based on the results of small-scale experiments,the optimal process parameters are determined,and referring to the successful experience of similar smelters in actual production,combined with the actual situation of the ore,the selection of equipment for the original ore circulating fluidized oxygen-enriched roasting section is studied,in order to obtain good design indicators.
