基于界面化学调控的尾矿固液分离药剂研究进展
Research progress on solid-liquid separation reagents for tailings based on interfacial chemistry regulation
摘要
Abstract
With the rapid growth of global demand for mineral resources,the production of tailings during mining development also significantly increases.Efficient solid-liquid separation technology is the foundation and key to the disposal of these large quantities of tailings,while the research and development of accurately matched solid-liquid separation reagents are the core to strength the process.In this paper,the key issues and technical difficulties in the tailings solid-liquid separation process,including flocculation sedimentation,thickening transportation,and filtration dewatering were comprehensively analyzed,the latest advancements in interfacial chemical regulation reagents involved in each step,and the interfacial chemical regulation mechanisms and performance enhancement mechanisms of these solid-liquid separation reagents were summarized.Finally,the development trends of tailings solid-liquid separation technology from the aspects of theoretical perfection,new technology development and multi-process collaborative enhancement were prospected,which can provide references and guidance for promoting the clean production of the mineral resources industry.关键词
