摘要 磨矿-浮选是一个复杂的物理化学反应体系,矿粒的表面性质和矿浆性质直接决定了矿物浮选的效果。为了提高磨矿效率、节能降耗,常在磨矿过程中添加具有助磨效果的化学试剂,但是助磨剂的掺入改变了矿物的表面性质和矿浆性质,对后续的浮选过程会产生不同的影响。助磨剂会对矿物的粒度、表面性质(晶体结构、表面形貌、表面电位和表面能等)和矿浆性质(黏度和pH值等)产生重要影响;从浮选动力学的角度来讲,助磨剂对上述因素的影响最终会导致矿粒在气泡表面上的碰撞与粘附概率发生变化,其作用机理有待进一步深入研究。本文基于已有文献资料,梳理了助磨剂影响矿物浮选和浮选动力学的主要作用机制及最新研究进展,以期为助磨剂在磨矿中的应用和浮选工艺的改进提供研究基础。

Abstract: Flotation is a complex physical and chemical process, the physical and chemical properties of mineral surface and pulp properties are the decisive factors affecting flotation. The addition of grinding aids in the grinding process can improve the grinding efficiency, which is conducive to energy saving, but the addition of grinding aids changes the physical and chemical properties of mineral surface and pulp properties, so it will have different effects on the subsequent flotation process. Grindingaids can have important effects on mineral particle size, surface properties (crystal structure, surface morphology, surface potential and surface energy, etc.) and pulp properties (viscosity and pH, etc.). From the perspective of flotation dynamics, the above factors affected by grinding aids will eventually change the collision and adhesion probability of mineral particles on the surface of bubbles, and its mechanism needs to be further studied. Based on the existing literature, this paper reviews the latest research progress of the effect of grinding aids on mineral flotation and flotation kinetics and its mechanism, in order to provide research basis for the application of grinding aids in grinding and the improvement of flotation process.
