Min Guowei; Luo Zhongxing(Central Eng. & Res. Institute for Non-Ferrous Metallurgical industries, Beijing, 100038)  
It is difficult to economically recover gold from refractory are using conventional processing and metallurgy processes. In this paper a review is made on the commercial techniques abroad for gold extraction from refractory ore in the past decade,and the possibilities are analyzed of introduction of these techniques into China.
