Method for manufacturing composite mineral admixture from ferromanganese ore tail mud
The invention discloses a method for manufacturing a composite mineral admixture from ferromanganese tailings, which comprises the following steps: step A, crushing ferromanganese tailings and quartz sand tailings, and processing the crushed ferromanganese tailings and quartz sand tailings into powder; B, mixing the powdery ferromanganese tailings with warm water, stirring, and successively adding a flocculating agent during stirring so as to prepare manganese iron ultrafine tail mud for later use; and C, respectively putting slag powder, quartz sand tailings and desulfurized gypsum into a stirrer in sequence, stirring and mixing for 3 hours, then adding manganese iron ultrafine tail mud, and stirring and mixing for 1 hour to obtain the composite mineral admixture; The manganese iron ultrafine tail mud is treated by the flocculating agent, so that the cohesiveness of the used composite mineral admixture can be improved, and a product prepared from the admixture is more durable; The preparation process is greatly shortened, meanwhile, waste such as slag powder is utilized, recycling is achieved, outward emission can be reduced, pollution to the environment is reduced, and the production cost can be saved.
本发明公开了一种通过锰铁矿尾泥制造复合矿物掺合料的方法，包括以下步骤：步骤A，将锰铁尾矿石与石英砂尾矿进行粉碎，加工成粉末状；步骤B，粉末状锰铁尾矿混合温水进行搅拌，且搅拌期间陆续加入絮凝剂，制成锰铁超细尾泥备用；步骤C，分别将矿渣粉、石英砂尾矿和脱硫石膏依次放入搅拌机，搅拌混合3小时，再加入锰铁超细尾泥搅拌混合1小时，即得复合矿物掺合料；通过絮凝剂处理锰铁超细尾泥，可以提高复合矿物掺合料使用后的粘结度，使得以此种掺和料制备的产物更耐用，且大大缩短了制备流程，同时利用矿渣粉等废弃物，做到再利用，能够减少向外排放，降低对环境的污染，能够节约生产成本。
