Embodiment 1
[0032] A method for processing waste refractory bricks containing vanadium, comprising the steps of:
[0033] S1: 500g of vanadium-containing waste refractory bricks (the mass content of vanadium is 3.0%) is crushed by a jaw crusher to a particle size of ≤25mm, and then ground by a ball mill until the particle size of the refractory brick powder after grinding is ≤125μm Accounting for the proportion of refractory brick powder total amount is 81.5%, then magnetic separation (magnetic separation magnetic field strength is 2.0T) obtains vanadium-containing refractory brick powder, and vanadium content is 3.68%;
[0034] S2: Mix the above vanadium-containing refractory brick powder with 7.5 g of sodium carbonate, grind to a particle size of ≤50 μm, and roast at 780° C. for 3 hours to obtain roasted clinker;
[0035] S3: adding the above-mentioned roasted clinker into 175g of water, leaching at 75°C for 2 hours to obtain a vanadium-containing slurry;
[0036] S4: Add 3.5g of alumi...
Embodiment 2
[0038] A method for processing waste refractory bricks containing vanadium, comprising the steps of:
[0039] S1: 800g of vanadium-containing waste refractory bricks (the mass content of vanadium is 7.2%) is crushed by a jaw crusher to a particle size of ≤25mm, and then ground by a ball mill until the particle size of the refractory brick powder after grinding is ≤125μm Accounting for the proportion of refractory brick powder total amount is 81.5%, then magnetic separation (magnetic separation field intensity is 2.3T) obtains vanadium-containing refractory brick powder, and vanadium content is 10.25%;
[0040] S2: Mix the above vanadium-containing refractory brick powder with 16g of sodium carbonate, grind to a particle size of ≤50 μm, and roast at 850°C for 3.5 hours to obtain roasted clinker;
[0041] S3: adding the above-mentioned roasted clinker into 400g of water, leaching at 90°C for 2.5h to obtain a vanadium-containing slurry;
[0042] S4: Add 10 g of aluminum sulfate ...
Embodiment 3
[0044] A method for processing waste refractory bricks containing vanadium, comprising the steps of:
[0045] S1: 500g of vanadium-containing waste refractory bricks (the mass content of vanadium is 20.0%) is crushed by a jaw crusher to a particle size of ≤25mm, and then ground by a ball mill until the particle size of the refractory brick powder after grinding is ≤125μm Accounting for the proportion of refractory brick powder total amount is 81.5%, then magnetic separation (magnetic separation magnetic field intensity is 2.5T) obtains vanadium-containing refractory brick powder, and vanadium content is 23.52%;
[0046] S2: Mix the above vanadium-containing refractory brick powder with 7.5g of sodium carbonate, grind to a particle size of ≤50 μm, and roast at 70°C for 4 hours to obtain roasted clinker;
[0047] S3: adding the above-mentioned roasted clinker to 200g of water, leaching at 60°C for 4 hours to obtain a vanadium-containing slurry;
[0048] S4: Add 4g of aluminum s...
