Example Embodiment
[0028] Example 1: see figure 1 , A high-acid leaching wet zinc smelting iron slag and blast furnace soot comprehensive recycling process, which includes the following steps:
[0029] (1) Preparation of raw materials: the mixed raw materials are prepared in a weight ratio of 20 parts of iron vitriol slag, 8 parts of sulfur concentrate, and 40 parts of blast furnace soot;
[0030] (2) Magnetized roasting: send the mixed raw materials through the conveyor belt into the hopper of the magnetized roasting boiling furnace to obtain slag; control the feeding speed to uniformly add the mixed raw materials into the magnetized roasting boiling furnace, the roasting temperature is about 800~900℃, The linear velocity of the wind is 0.3~0.6m / s, the air excess coefficient is -2~5%, and the sulfur dioxide concentration of the roasting flue gas is 8-10%; the roasting flue gas is sent to the acid plant system after the waste heat recovery of the waste heat boiler and the dust recovery;
