对微山稀土矿全尾砂充填进行的试验研究表明，用全尾砂作为充填材料与脱泥尾砂相比，没有明显的不利因素；全尾砂更容易得到均质浆体，具有较好的输送和析水特性。采用局部流态化吸出式、立式砂仓造浆，可实现高浓度及自流输送
The experimental study on the tailings filling in the Weishan rare earth mine shows that there is no obvious unfavorable factor when using the tailings as the stuffing material compared with the tailing sand removal; the tailings are easier to obtain a homogeneous slurry, which is better Conveying and water analysis. Using local fluidized suction type, vertical silos pulp, high concentration and gravity can be achieved
