| titleOfInvention | Barium slag harmless recycling treatment method and prepared building material |
| abstract | The application relates to a barium slag harmless resource treatment method and a prepared building material, and the method comprises the following steps: dissolving a proper amount of oxidant, ferrous sulfate, magnesium sulfate and dispersant in water to obtain a stabilizer solution; adding a proper amount of barium slag, medium coarse sand and quicklime into an edge runner mill, adding a stabilizer solution into the edge runner mill, supplementing a proper amount of water, and uniformly mixing to obtain a first mixture; adding a proper amount of sodium hydroxide, fly ash, gypsum, cement and magnesium oxide into the first mixture for continuous mixing to obtain a second mixture; and (5) vibrating and pressing the second mixture for forming, and moisturizing and curing to obtain the barium slag building material. According to the method, wheel milling equipment is utilized, barium slag is subjected to harmlessness and resource recovery in the same equipment step by step, excessive soluble sulfate is utilized to fix barium step by step, meanwhile, magnesium oxide is added later to eliminate the influence of soluble magnesium sulfate on the performance of building materials, and the barium ion leaching toxicity of the obtained barium slag building material is low and is as low as about 0.3mg/L as possible. |
