Embodiment 2
[0035] Example 2: The solidification method of this copper sludge, concrete operation is as follows:
[0036] (1) The copper sludge of a copper smelter used in this embodiment, the Isa slag of a certain copper smelter, and the fly ash composition are the same as in Example 1;
[0037] (2) After the copper sludge is naturally air-dried, pulverized and mixed, the sludge is subjected to microwave heating treatment at 600°C for 0.5h, and the copper sludge with a mass percentage of 20%, the Isa slag with a mass percentage of 35%, and the slag with a mass percentage of 20% Fly ash and ordinary Portland cement with a mass percentage of 25% were mixed and mixed for 25 minutes. During the mixing and grinding process, 7% lime was added to the mixture. After mixing and grinding, water and additives were added to the material. The addition of water The amount is 0.177% of the mass of cement and fly ash. The additive and water are added to the mixed and ground material at the same time. ...
Embodiment 3
[0040] Example 3: The solidification method of this copper sludge, concrete operation is as follows:
[0041] (1) The copper sludge of a copper smelter used in this embodiment, the Isa slag of a certain copper smelter, and the fly ash composition are the same as in Example 1;
[0042](2) After the copper sludge is naturally air-dried, pulverized and mixed, the sludge is subjected to microwave heating treatment at 400°C for 0.8h, and the copper sludge with a mass percentage of 30%, the Isa slag with a mass percentage of 20%, and the slag with a mass percentage of 35% Fly ash and ordinary Portland cement with a mass percentage of 15% were mixed and mixed and ground for 30 minutes. During the mixing and grinding process, 9% lime was added to the mixture. Water and additives were added to the material after mixing and grinding. The addition of water The amount is 0.2% of the mass of cement and fly ash, and the additive and water are added to the mixed and ground material at the ...
