Method for manufacturing composite mineral admixture by treating ferromanganese superfine tail mud with flocculating agent
The invention discloses a method for manufacturing a composite mineral admixture by treating ferromanganese superfine tail mud with a flocculating agent. The method comprises the following steps: step A, adding a flocculating agent into the ferromanganese ore beneficiation muddy water, carrying out solid-liquid separation after flocculent precipitation is carried out for a period of time, and taking ferromanganese superfine tail mud flocculate for later use; step B, adding quartz stone powder and limestone powder into the superfine ferromanganese tail mud flocculate obtained in the step A, fully and uniformly mixing the components and drying the mixture to obtain a semi-finished product; step C, mixing the semi-finished product obtained in the step B with fly ash and cement clinker, and adding the mixture into a mill for grinding; step D, homogenizing the ground material obtained in the step C through a homogenizing silo, and aging the homogenized ground material for 7-10 hours to obtain the composite mineral admixture. According to the method, the ferromanganese superfine tail mud which is difficult to utilize in the prior art is used as the main raw material of the composite mineral admixture, so that the resource utilization rate is increased; meanwhile, the production cost of the admixture is effectively reduced, so that the method is economical and environmentally friendly.
本发明公开了絮凝剂处理锰铁超细尾泥制造复合矿物掺合料的方法，包括以下步骤：步骤A，在锰铁矿选矿泥水中加入絮凝剂，絮凝沉淀一段时间后进行固液分离，取锰铁超细尾泥絮凝物备用；步骤B，在步骤A得到的锰铁超细尾泥絮凝物中加入石英石粉及石灰石粉，充分混匀后烘干制得半成品；步骤C，将步骤B得到的半成品与粉煤灰及水泥熟料混合加入磨机进行粉磨；步骤D，将步骤C得到的粉磨物料通过均化库进行均化，均化后的粉磨物料陈伏7‑10h即得复合矿物掺合料。本发明的方法将现有技术中难以利用的锰铁超细尾泥作为复合矿物掺合料的主要原料，在提高资源利用率的同时还有效降低了掺合料的生产成本，经济环保。
