Example Embodiment
[0034] Example 1
[0035] This embodiment is used to illustrate the method for recycling the blast furnace slag iron of the present invention.
[0036] Use a 2 ton weight hammer to crush the blast furnace slag iron (with a particle size of 1000-5000 mm) with an iron content of 20% by weight to below 100 mm, and then use a 20 mm vibrating sieve to screen to obtain a powder with a particle size of less than 20 mm And blocks with a particle size greater than 20 mm.
[0037] Add the powder to a ball mill (purchased from Shanghai Minggong Heavy Equipment Co., Ltd., model In ), ball milling is performed for 8 minutes, and then the ball milled powder is magnetically separated by a magnetic separator to obtain magnetic powder and non-magnetic powder.
[0038] 52 parts by weight of vanadium ilmenite concentrate, 27 parts by weight of ordinary iron concentrate, 52 parts by weight of coke powder, 15 parts by weight of quicklime and 1 part by weight of the magnetic powder are distributed on a ma...

[0044] Example 2
[0045] This embodiment is used to illustrate the method for recycling the blast furnace slag iron of the present invention.
[0046] Crush the blast furnace slag iron (with a particle size of 1000-5000 mm) with an iron content of 40% by weight with a 5 ton hammer to below 100 mm, and then screen it with a 20 mm vibrating screen to obtain a powder with a particle size of less than 20 mm And blocks with a particle size greater than 20 mm.
[0047] Add the powder to a ball mill (purchased from Shanghai Minggong Heavy Equipment Co., Ltd., model In ), ball milling is performed for 10 minutes, and then the ball-milled powder is magnetically separated by a magnetic separator to obtain magnetic powder and non-magnetic powder.
[0048] 51 parts by weight of vanadium ilmenite concentrate, 27 parts by weight of ordinary iron concentrate, 52 parts by weight of coke powder, 15 parts by weight of quicklime and 2 parts by weight of the magnetic powder are distributed on a magneti...
