Abstract
Hydrochloric acid leaching of Low-grade bauxite with high content of iron oxide was studied at atmospheric conditions and pressure conditions. The results indicate that the alumina extraction rate is lower at atmospheric conditions, and the extraction rate less than 51.5% at the condition with 99 – leaching temperature, 180 min leaching time and liquid to solid ratio at 3:1. Under pressure, the alumina extraction rate increased significantly with increasing the leaching temperature. When the leaching time is 60 min, liquid to solid ratio is 4:1, leaching temperature is 160 –, the alumina extraction rate reach 98.35%.
