Electrolytic manganese residue-chromium residue synergetic recycling utilization method and prepared cementing material
The invention discloses an electrolytic manganese residue-chromium residue collaborative resource utilization method and a prepared cementing material, and the method comprises the following steps: S1, mixing a part of carbide slag with electrolytic manganese residue slurry, carrying out deamination treatment to obtain deaminated manganese residue and ammonia gas, and recovering the ammonia gas; s2, mixing and ball-milling the deaminated manganese slag, chromium slag and the other part of carbide slag to obtain a mechanically modified mixed raw material; s3, stirring and mixing the mechanically modified mixed raw materials with water to obtain the medium-calcium system cementing material. The calcium system cementing material is prepared through synergistic curing of the electrolytic manganese residues and the chromium residues, harmless treatment and building material utilization of the electrolytic manganese residues and the chromium residues are achieved, pollution to the surrounding environment is avoided, and a large number of land resources are prevented from being occupied.
本发明公开一种电解锰渣‑铬渣协同资源化的利用方法及制备的胶凝材料，包括以下步骤：S1.将一部分电石渣与电解锰渣浆料混合，进行脱氨处理，得到脱氨锰渣及氨气，将氨气进行回收；S2.将脱氨锰渣与铬渣、另一部分电石渣混合球磨，得机械改性混合原料；S3.将机械改性混合原料与水搅拌混合，即得中钙体系胶凝材料；通过电解锰渣—铬渣协同固化制备中钙体系胶凝材料实现了电解锰渣和铬渣无害化处理和建材化利用，避免对周围环境产生污染并占用大量土地资源。
