it was noted that the suitable addition of type yj-2 dewatering agent can in-crease the 28d strength of cemented filling material with unclassified tailings and its flowability.
指出,加入适量的yj一2型减水剂,对全尾砂胶结充填料的28天强度和流动性均有改善。
according to the physicochemical properties of unclassified tailings in wudaoling molybdenum mine, the anionic polyacrylamide is used as a flocculant for precipitation.
根据五道岭钼矿全尾砂浆体物理化学性质,选择了阴离子聚丙烯酰胺作全尾砂沉淀的絮凝剂。
filling with unclassified tailings will expand the supply of filling materials with no need to build a dam for fine tailings.
全尾砂充填可解决两个问题:增加充填料来源和免去为细尾砂筑坝堆放。
