N2 - Dynamics of bubble in froth flotation have been studied. The purpose of this research is to study the effects of pine oil on the dynamics of small bubble in froth flotation. Dynamics of bubble is an important parameter which determines flotation eficiency. Acrylic pipe was setup as a flotation column and equipped with image capture and lighting equipments. Later on, bubble was generated by a nozzle. A different nozzle size and pine oil concentrations were used in this experiment. Eventually, the dynamics of the bubble were captured by camera and the images were then processed by image processing software. Therefore, bubble's size and its position can be determined. The results indicate that bubble movement can be divided into three stages: acceleration, deceleration and terminal velocity. It is also indicated that pine oil modify surface tension; hence the bubble size become smaller and its velocy decrease. Moreover, pine oil induces the bubble to reach terminal velocity faster then bubble in water wthout pine oil. Therefore, it can be concluded that pine oil affects bubble dynamics significantly.
