摘要
本文分析讨论浮选过程矿粒-气泡的相互作用,并对作用势能作了计算。认为疏水作用在矿粒-气泡粘着过程中具有支配性地位;所谓无接触粘着仅在一定条件下发生于亲水矿粒-气泡体系;无接触粘着对浮选过程的正常进行有害。
In this paper,the particle-bubble interaction in flotation is analyzed and the potential energies of interaction are calculated. It was found that the hydrophobic interaction plays a predominant role in particle-bubble attachment. The so called contactless attachment happens just in case of hydrophilic particle-bubble system in proper conditions and is harmful to normal flotation.
