WebThe results of the leaching tests with different acids indicate that H 2 SO 4 and HCl seem to be the most effective leaching media for lithium leaching, with or without the addition of H 2 O 2. Nevertheless, the experiments with C 2 H 2 O 4 highlight its selectivity for lithium, which offers the possibility for a two-step leaching process that ... WebAug 31, 2024 · The best leaching conditions were 0.235 lb of HCl and 0.172 lb Cl2 per pound of matte, followed by the addition of oxygen to the slurry at 90° to 106° C with an overpressure of 48 psig. The total reaction time for the PDU apparatus was 1 hour because the slurry had to be heated to increase the oxygen reaction rate. Copper extraction was …
