| Abstract: | As for a kind of low-grade beryllium ores containing 0.515% beryllia from Xinjiang, a process of microwave heating was adopted for pretreatment in the test, and the influences of factors, including temperature and time for microwave heating, concentration of sulfuric acid and time for oscillation leaching, on beryllium leaching rate were investigated. Results show that, after pretreatment by microwave heating at 230 ℃ for 4 h, with beryllium ore and concentrated sulfuric acid in a mass ratio of 1∶1.4, oscillation leaching for 4 h, the beryllium leaching rate reaches 96.7%. It is concluded that such processing technique can be taken as a new approach for the exploitation and utilization of such low-grade beryllium ore. |
