| Abstract: | For a micro-fine disseminated and refractory gold ore in Qinghai province, with high As and low cyanide leaching, an experiment research was carried out for its comprehensive recovery processing. After comparing three different flow-sheets, a full flotation separation process was finally achieved, by once-roughing, twice-scavenging and twice-cleaning under coarse grinding and weak acidic condition. The gold grade of the final concentrate was 48.2g/t, with gold recoverv rate of 87.15%. |
