Method for producing artificial rich iron ore from nickel smelting waste slag by utilizing new sintering process

[0023] a. Pour the nickel smelting waste slag at 1200°C into the hot slag bag, shake the bag for 10 minutes and then let it stand for 15 minutes;

[0024] b. Remove the floating slag part of the uppermost layer of the hot slag bag accounting for 5% of the total volume of the discarded slag, keep the bottom slag part of the bottom layer of the hot slag bag accounting for 5% of the total volume of the discarded slag, and transfer the rest of the hot slag bag to another in hot slag bag;

[0025] c. Add iron concentrate powder with an iron content of 62% in the above-mentioned hot slag bag containing most of the waste slag. The consumption of iron fine powder is 50% of the total weight of the waste slag in the hot slag bag, and then stir evenly. Make the iron fine powder evenly melt in the waste slag;

[0026] d. Pour the waste slag with iron concentrate powder into the mold to cool, then crush, sieve, and finish it to be used as a qualified artificial iron-rich ore.

[0029] a. Pour the nickel smelting waste slag at a temperature of 1100°C into the hot slag bag, shake the bag for 5 minutes and then let it stand for 10 minutes;

[0030] b. Remove the floating slag part of the uppermost layer of the hot slag bag accounting for 3% of the total volume of the discarded slag, keep the bottom slag part of the bottom layer of the hot slag bag accounting for 3% of the total volume of the discarded slag, and transfer the rest of the hot slag bag to another in hot slag bag;

[0031] c. Add iron oxide scales with an iron content of 60% to the above hot slag bag containing most of the waste slag. The amount of iron oxide scale is 30% of the total weight of the waste slag in the hot slag bag. The iron sheet is evenly melted in the waste slag;

[0032] d. The waste slag added with iron scale is then cooled by a cast iron machine, and then crushed, screened, and finished to be used as a qualified artificial iron-rich ore.

[0035] a. Pour the nickel smelting waste slag at a temperature of 1300°C into the hot slag bag, shake the bag for 15 minutes and then let it stand for 20 minutes;

[0036] b. Remove the floating slag part of the uppermost layer of the hot slag bag accounting for 8% of the total volume of the discarded slag, keep the bottom slag part of the bottom layer of the hot slag bag accounting for 8% of the total volume of the discarded slag, and transfer the rest of the hot slag bag to another in hot slag bag;

[0037] c. Add iron-rich ore powder with an iron content of 65% in the above-mentioned hot slag bag containing most of the waste slag. The amount of iron-rich ore powder is 100% of the total weight of the waste slag in the hot slag bag, and then stir Evenly, so that the iron-rich ore powder is evenly melted in the waste slag;

[0038] d. The waste slag added with iron-rich ore powder is cooled with an iron casting machine, and then crushed, screened, and finished to be used as a...
