[0047]Such as figure 1 Shown, a kind of lead smelting slag provided by the present invention enters the preparation method of furnace grain, specifically comprises the following steps:
[0048] Step 1, weighing the following raw materials according to mass percentage: 2-10% of soot, 60-70% of lead concentrate, 18-22% of lead-silver slag, 5-10% of pyrite and 2-5% of sulfur;
[0049] Among them, the moisture content of soot, lead concentrate, lead-silver slag and pyrite is 6-13%.
[0050] Preferably, the moisture content of the soot, lead concentrate, lead-silver slag and pyrite is all 9%.
[0051] Step 2, putting the soot, lead concentrate, lead-silver slag and pyrite weighed in step 1 into a blender and adding water to carry out drum mixing to obtain a mixed prediction;
[0052] Among them, the expected moisture content of the mixture is 8-9%, and the overall particle size is 60-200 mesh;
[0053] In step 3, a vertical press or a ball press is used to press the mixed materi...
Embodiment 1
[0088] A kind of preparation method that the lead smelting slag that the invention provides enters furnace grain, specifically comprises the following steps:
[0089] Step 1, weighing the following raw materials according to mass percentage: 2% of total soot content, 60% of lead concentrate, 18% of lead-silver slag, 5% of pyrite and 2% of sulfur;
[0090] Step 2, putting the soot, lead concentrate, lead silver slag and pyrite weighed in step 1 into a blender for forced mixing to obtain a mixed prediction;
[0091] Among them, the expected moisture content of the mixture is 8%, and the overall particle size is 60 mesh;
[0092] In step 3, a vertical press or a ball press is used to press the mixed material prepared in step 2 to obtain furnace pellets of lead smelting slag.
Embodiment 2
[0094] A kind of preparation method that the lead smelting slag that the invention provides enters furnace grain, specifically comprises the following steps:
[0095] Step 1, weighing the following raw materials according to mass percentage: 10% of the total content of soot, 70% of lead concentrate, 22% of lead and silver slag, 10% of pyrite and 5% of sulfur;
[0096] Step 2, putting the soot, lead concentrate, lead silver slag and pyrite weighed in step 1 into a blender for forced mixing to obtain a mixed prediction;
[0097] Among them, the expected moisture content of the mixture is 9%, and the overall particle size is 200 mesh;
[0098] In step 3, a vertical press or a ball press is used to press the mixed material prepared in step 2 to obtain furnace pellets of lead smelting slag.
