Pellet prepared through magnesium smelting waste

[0016] The pellets of Example 1 were manufactured according to the following steps:

[0017] (1) Mix 100 grams of iron-containing dust, 0.5 grams of magnesium reduction slag powder (dicalcium silicate), 0.1 grams of magnesium refining slag (magnesium chloride) and 8 grams of Portland cement.

[0018] (2) Add 10 grams of water to each 100 grams of the mixture, and use a PanPelletizer to make pellets with a particle size of 25 mm.

[0019] (3) The pellets are dried, cured and cured.

[0020] The five pellet samples made according to the above steps were tested for compressive strength. The results are shown in Table 1.

[0024] The pellets of Example 2 were manufactured according to the following steps:

[0025] (1) Mix 100 grams of iron ore powder, 1 grams of magnesium reduction slag powder (dicalcium silicate), 0.5 grams of magnesium refining slag (magnesium chloride) and 9 grams of Portland cement.

[0026] (2) Add 15 grams of water to each 100 grams of the mixture, and use a PanPelletizer to make pellets with a particle size of 22 mm.

[0027] (3) The pellets are dried, cured and cured.

[0028] The 5 pellet samples made according to the above steps were tested for compressive strength. The results are shown in Table 2.

[0032] The pellets of Example 3 were manufactured according to the following steps:

[0033] (1) Refining 100 grams of iron dust sludge and iron ore powder mixture, the mass ratio of iron dust sludge to iron ore powder is 5:5, 3 grams of magnesium reduction slag powder (dicalcium silicate), 1 gram of magnesium The slag (magnesium chloride) and 10 grams of Portland cement are mixed evenly

[0034] (2) Add 20 grams of water to every 100 grams of the mixture, and make pellets with a particle size of 18 mm using a pan pelletizer.

[0035] (3) The pellets are dried, cured and cured.

[0036] The five pellet samples made according to the above steps were tested for compressive strength. The results are shown in Table 3.
