| Abstract: | Guobaoshan rubidium ore was roasted and rubidium was multi-stage alkaline leached from calcining with Rb2O grade of 0.1%. The results show that average rubidium leaching rate is 93.87% and average calcium removal rate is 99.76% under the optimum conditions including sodium carbonate dosage of 1.4 times of theoretical amount, ratio of liquid to solid of 2, room temperature, leaching duration of 1.5 h, and multi-stage circulation times of five. |

| Keywords: | rubidium calcining multi-stage circulation alkaline leaching calcium removal |
