珍珠岩尾矿复合聚渣剂的制备及应用

Preparation and Application of Perlite Tailings Compound Slag Conglomeration Agent

以珍珠岩尾矿为主要原料,通过加入粘结剂,混合均匀后烧结成块,然后进行破碎和筛分,制备出珍珠岩尾矿复合聚渣剂。通过设计研究不同配方的珍珠岩复合聚渣剂并进行试验优化。研究结果表明:珍珠岩尾矿复合聚渣剂配方主要组成为8%活性SiO2、4%活性Al2O3、4%水玻璃和珍珠岩尾矿,其在铁液中的铺展效果、聚渣效果以及扒渣效果与单一珍珠岩聚渣剂相比更优异。珍珠岩尾矿复合聚渣剂的应用提高了珍珠岩尾矿的利用率,实现了废弃资源的再利用。

The perlite tailings compound slag conglomeration agent were prepared,and the main processes were as follows:the perlite tailings were used as the main raw material,the binder was added in the perlite tailings and sintered into blocks after mixing evenly,and then the blocks were broken and separated.This study investigated the effect of slag conglomeration agent composition on the application effect.The results shows that the spreading ability in iron liquid,slag conglomeration and slagging-off effects of the perlite tailings compound slag agent are better than those of the single perlite slag agent when the composition of the compound slag agent was 8%activity SiO2,4%activity Al2O3,4%sodium silicate and the rest pearlite tailings.The application of the perlite tailings compound slag conglomeration agent can improve the utilization rate of perlite tailings and realize the reuse of waste resources.
