Abstract

Abstract

This paper investigated leaching rubidium and lithium from a mica rough concentrate by roasting-water leaching combined process. The effects of additives dosage, roasting temperature, roasting time, leaching temperature and leaching time on leaching rates of rubidium and lithium were studied. As a result, the optimal process parameters were determined as additives dose of 90% (w.t) ore, roasting temperature of 950℃, roasting time of 1.5 h, leaching temperature of 30℃ and leaching time of 1.5 h. Under these conditions, the leaching rates of rubidium and lithium were larger than 95% and 90%, respectively.
