Embodiment 1
[0048] 1) Ball mill: After mixing water cobalt ore with a certain proportion of water (volume ratio of water cobalt ore and water: 1:3), it enters the ball mill through an automatic feeder for wet grinding, and the particle size of the ground pulp reaches -100 Requirements for pulp, 80% passing rate;
[0049] 2) Mixing: Put the pulp through the pulp pump and cobalt sulfide slag into the mixing tank according to the weight ratio of 3:1 and mix for 1 hour, so that the two kinds of raw cobalt materials are evenly mixed;
[0050] 3) Leaching: Add concentrated sulfuric acid into the stirring tank with the mixed solution through the flow guide tube at a flow rate of 100-120L / min, keep the stirring speed at 75-100r / min, and the initial concentration of concentrated sulfuric acid is 180 / L, Add steam to increase the reaction temperature, and carry out the oxidation→reduction reaction at a controlled temperature of 80~90°C for 8~10 hours. After cobalt and other metals enter the solution...
Embodiment 2
[0055] 1) Ball mill: After mixing water cobalt ore with a certain proportion of water (volume ratio of water cobalt ore and water: 1:3), it enters the ball mill through an automatic feeder for wet grinding, and the particle size of the ground pulp reaches -100 Requirements for pulp, 80% passing rate;
[0056] 2) Mixing: Put the pulp through the pulp pump and cobalt sulfide slag into the mixing tank according to the weight ratio of 3:1 and mix for 1 hour, so that the two kinds of raw cobalt materials are evenly mixed;
[0057] 3) Leaching: Add hydrochloric acid into the stirring tank with the mixed solution through the flow guide tube at a flow rate of 100-120L / min, keep the stirring speed at 75-110r / min, and the initial concentration of hydrochloric acid is 165g / L. Carry out oxidation→reduction reaction at 50-75°C for 8~10 hours, after cobalt and other metals enter the solution in an ion state, take a sample for detection and analysis. %, the reaction is stopped, and the liqu...
Embodiment 3
[0062] 1) Ball mill: After mixing water cobalt ore with a certain proportion of water (volume ratio of water cobalt ore and water: 1:3), it enters the ball mill through an automatic feeder for wet grinding, and the particle size of the ground pulp reaches -80 Requirements for pulp, 95% passing rate;
[0063] 2) Mixing: Put the slurry through the slurry pump and cobalt sulfide slag into the mixing tank according to the weight ratio of 3:2 and mix for 1 hour, so that the two kinds of raw cobalt materials are evenly mixed;
[0064] 3) Leaching: Add the concentrated sulfuric acid into the stirring tank with the mixed solution through diversion at a flow rate of 100-120L / min, keep the stirring speed at 85-120r / min, and the initial concentration of concentrated sulfuric acid is 150g / L. Carry out the oxidation→reduction reaction at a temperature of 70-90°C for 7-9 hours, so that cobalt and other metals enter the solution in an ion state, and then take samples for detection and analys...
