After 50 cycles, the capacities of the samples remained at 90, 125, 106 and 82 mAh g −1, and their capacity retentions were 81.8%, 94.7%, 86.9% and 71.3%, respectively.
High acid consumption is a common problem in the treatment of low-grade Mn carbonate ores by H 2 SO 4 leaching process. In this study, Fe 2 (SO 4) 3 solution was used to replace the commonly used H 2 SO 4 solution as a leaching agent to leach Mn from low-grade Mn carbonate ores, and therefore the acid consumption was reduced. Simultaneously, …
