摘要
主要针对微细粒矿物作为研究对象,基于PEO聚氧化乙烯状态下的类聚絮凝以及浮选分离进行研究.通过展开相应的试验,探究微细粒矿物在浮选过程中所存在的类聚强化反应.通过对微细粒矿物浮选过程中的类聚强化表现进行研究,发现联合使用100万分子量的PEO以及KEX能够强化浮选回收混合矿物中的微细粒矿物,从而达到较高的浮选分离效率.并对两种不同的加药顺序进行研究,发现在实际当中"KEX+PEO"的加药顺序相较于"PEO+KEX"具有更加良好的絮凝作用,有利于对矿物加以浮选,因此进一步证明了能够通过类聚絮凝方式提升微细粒矿物浮选分离效率.
Abstract
Mainly targeting fine-grained minerals as the research object,the study is based on the aggregation flocculation and flotation separation of PEO in the state of polyethylene oxide.By conducting corresponding experiments,explore the aggregation strengthening reactions of fine-grained minerals in the flotation process.By studying the aggregation enhancement performance during the flotation process of fine-grained minerals,it was found that the combined use of PEO with a molecular weight of 1 million and KEX can enhance the flotation recovery of fine-grained minerals in mixed minerals,thereby achieving high flotation separation efficiency.And two different dosing sequences were studied,and it was found that in practice,the dosing sequence of"KEX+PEO"has a better flocculation effect compared to"PEO+KEX",which is conducive to flotation of minerals.Therefore,it further proves that the flotation separation efficiency of fine-grained minerals can be improved through aggregation flocculation.
