Embodiment 1
[0027] The present invention comprehensively reclaims the processing method of high manganese cobalt ore, and is made up of following processing steps:
[0028] (1) Reductive leaching step: put 1000 grams of cobalt ore crushed to 150 microns and 22% manganese into clear water at a liquid-solid weight ratio of 3:1, stir to form a slurry, and The temperature of the slurry is raised to 50°C, and then 220 grams of sodium thiosulfate and 396 grams of concentrated sulfuric acid are slowly added at the same time. The reduction leaching reaction time is controlled at about 4 hours, and the pH is always controlled at 1-2.5 during the reaction process. After the reaction is completed, filter to obtain the filtrate As a backup, the filtrate contains valuable metal ions: Mn 2+ 、Co 2+ 、Ni 2+ 、Cu 2+ and impurity metal ions: Fe 3+ , Zn 2+ 、Al 3+ , Mg 2+ , Ca 2+ 、Na + etc., discard the filter residue;
[0029] (2) preliminary purification step: the standby filtrate of step (1) gaine...

[0037] The present invention comprehensively reclaims the processing method of high manganese cobalt ore, and is made up of following processing steps:
[0038] (1) Reduction leaching step:
[0039] Put 1000 grams of cobalt ore crushed to 100 microns and with a manganese content of 30% into clear water at a liquid-solid weight ratio of 4:1, stir to form a slurry, and heat the slurry to 60°C, then Slowly add 300 grams of sodium thiosulfate and 540 grams of concentrated sulfuric acid at the same time, the reduction leaching reaction time is controlled at about 5 hours, and the pH is always controlled at 1-2.5 in the reaction process, and the filtrate is obtained by filtering after the reaction as a standby. Valuable metal ions: Mn 2+ 、Co 2+ 、Ni 2+ 、Cu 2+ and impurity metal ions: Fe 3+ , Zn 2+ 、Al 3+ , Mg 2+ , Ca 2+ 、Na + etc., discard the filter residue;
[0040] (2) Preliminary purification steps:
[0041] The standby filtrate of step (1) gained is transferred to pr...
Embodiment 3
[0050] The present invention comprehensively reclaims the processing method of high manganese cobalt ore, and is made up of following processing steps:
[0051](1) Reduction leaching step:
[0052] Put 1000 grams of cobalt ore crushed to 75 microns and containing 43% manganese into clear water at a liquid-solid weight ratio of 5:1, stir to form a slurry, and heat the slurry to 80°C. Slowly add 430 grams of sodium thiosulfate and 774 grams of concentrated sulfuric acid, the reaction time of reduction leaching is controlled at about 6 hours, and the pH is always controlled at 1-2.5 during the reaction process, and the filtrate is obtained by filtering after the reaction as a backup. The filtrate contains Valence metal ion: Mn 2+ 、Co 2+ 、Ni 2+ 、Cu 2+ and impurity metal ions: Fe 3+ , Zn 2+ 、Al 3+ , Mg 2+ , Ca 2+ 、Na + etc., discard the filter residue;
[0053] (2) Preliminary purification steps:
[0054] The standby filtrate of step (1) gained is transferred to prelimi...
