Physical properties such as particle morphology (shape and roughness) play an important role in the flotation process to understand the bubble-particle and particle–particle interactions. In this study, a new approach was suggested for the first time to correlate the aggregation and flotation of sphalerite mineral along with the contribution of morphological variations. Towards this aim, fine particles of −74 + 38 μm were produced with a ball mill while the effect of grinding time was investigated on morphology. In addition to the grinding, the roughness of particles was tuned through an abrasion treatment with silicon carbide. The shape factor of particles determined by image analysis and the roughness of particles measured with profilometer were also correlated with the micro-flotation experiments and aggregation analyses. The bubble-particle attachment time and fast-cam recordings were used to shed light on the possible mechanisms, i.e. roughness played a major role in its contribution of morphology on both flotation and aggregation of particles which were supported by fast-cam recordings as the larger bundle of particles and lower attachment time on bubble-particle attachment timer. In sum, adjusting the morphology of sulfide particles enhanced particle–particle interactions (aggregation) and led to improved bubble-particle interactions and in turn to flotation.

诸如颗粒形态（形状和粗糙度）之类的物理属性在浮选过程中起着重要作用，以了解气泡-颗粒和颗粒-颗粒之间的相互作用。在这项研究中，首次提出了一种新的方法来关联闪锌矿矿物的聚集和浮选以及形态变化的影响。为了达到这个目的，用球磨机生产了-74 + 38μm的细颗粒，同时研究了研磨时间对形态的影响。除了研磨之外，还通过用碳化硅进行的研磨处理来调整颗粒的粗糙度。通过图像分析确定的颗粒形状因子和用轮廓仪测量的颗粒粗糙度也与微浮选实验和聚集分析相关。气泡-颗粒附着时间和快速摄像记录用于阐明可能的机理，即粗糙度在其形态对浮选和聚集的形态贡献中起主要作用，快速摄像记录支持较大的颗粒束粒子，并减少气泡粒子附着计时器上的附着时间。总之，调整硫化物颗粒的形态可增强颗粒间的相互作用（聚集），并改善气泡-颗粒间的相互作用，进而导致浮选。粗糙度在其对浮选和聚集的形态学贡献中起着主要作用，这由快速摄像记录来支持，因为较大的颗粒束和较短的气泡-颗粒附着计时器的附着时间。总之，调整硫化物颗粒的形态可增强颗粒间的相互作用（聚集），并改善气泡-颗粒间的相互作用，进而导致浮选。粗糙度在其对浮选和聚集的形态学贡献中起着主要作用，这由快速摄像记录来支持，因为较大的颗粒束和较短的气泡-颗粒附着计时器的附着时间。总之，调整硫化物颗粒的形态可增强颗粒间的相互作用（聚集），并改善气泡-颗粒间的相互作用，进而导致浮选。
