Embodiment 1
[0035] A method for comprehensive recovery and utilization of multiple valuable elements in blast furnace gas mud, the process flow chart is shown in figure 1 , including the following steps:
[0036] 1) Put the blast furnace gas mud into a drying oven, dry it at 120°C for 36 hours, and grind it with a planetary ball mill for 2 hours to obtain gas ash with a particle size of less than 0.1 μm;
[0037] 2) add water to the gas ash obtained in step 1) to make the pulp concentration 6wt%, stir evenly, add collector diesel oil and foaming agent 2# oil to the obtained slurry (the amount of collector relative to gas mud is 7wt%; The consumption of foaming agent relative to the gas mud is 4wt%) then add unslaked lime to adjust the pH value of the resulting slurry to 11, carry out a rough separation three times to concentrate and collect carbon slurry and tailings; Drying under high temperature for 24 hours, then adding 5 times the dilute sulfuric acid with a mass concentration of car...
Embodiment 2
[0049] A method for comprehensive recycling of multiple valuable elements in blast furnace gas mud, specifically comprising the following steps:
[0050] 1) Put the blast furnace gas mud into a drying oven, dry it at 120°C for 36 hours, and grind it with a planetary ball mill for 2 hours to obtain gas ash with a particle size of less than 0.1 μm;
[0051] 2) Add water to the gas ash obtained in step 1) to make the slurry concentration 6%, stir evenly, add collector diesel oil and foaming agent 2# oil to the obtained slurry, and the amount of collector relative to the gas mud is 7% by mass %; The amount of foaming agent relative to gas mud is 4% by mass fraction. Then add quicklime to adjust the pH value of the obtained slurry to 12, carry out a rough separation three times to collect the carbon slurry and tailings; filter the collected carbon slurry and dry it at 120°C for 24 hours, and then add 5 times the amount of carbon The mass concentration of ore mass is that the dilut...
