摘　　要：随着易采选矿产资源越来越少,贫细杂矿石成为我们主要的回收资源。本文针对细粒矿产资源流失严重、细粒矿物难选的问题,设计合成识别和选择性捕获目的矿物的疏水性纳米粒子、研究纳米粒子与矿物间界面的相互作用的微观机理以及与气泡的相互作用机制,开发疏水性纳米粒子作为浮选捕收剂回收细粒矿物的新工艺。With less and less mineral resources for easy mining,lean and fine ore has become our main recycling resource.In order to solve the problem of serious loss of fine-grained mineral resources and difficult selection of fine-grained minerals,this paper designs and synthesizes hydrophobic nanoparticles that identify and selectively capture the target minerals,and studies the microscopic mechanism of the interaction between nanoparticles and minerals and the interaction with bubbles The mechanism of action is to develop a new process for recovering fine-grained minerals by using hydrophobic nanoparticles as a flotation collector.
