J. Cent. South Univ. (2018) 25: 3021-3032 DOI: https://doi.org/10.1007/s11771-018-3971-9 Effects of initial bubble size on geometric and motion characteristics of bubble released in water KANG Can... Germany, part of Springer Nature 2018 Abstract: To seek and describe the influence of bubble size on geometric and motion characteristics of the bubble, six nozzles with different outlet diameters were......
A novel approach to prevent bubble coalescence during measurement of bubble size in flotationZHANG Wei(张炜)1, 2, Jan E. Nesset2, James A. Finch2(1. Mining and Mineral Resources Division, Department...:Effect of frothers in preventing bubble coalescence during flotation of minerals has long been investigated. To evaluate the performance of a frother, an apparatus to measure the bubble size is a basic......

Bubble size as a function of some situational variables in mechanical flotation machinesZHANG Wei(张炜)1, 2, Jan E. Nesset2, James A. Finch2(1. Mining and Mineral Resources Division, Department...:The specific results of the work investigating the effect of gas density and water temperature on bubble size were present. These were surrogate variables designed to investigate the effect of viscosity......
Correspondence of bubble size and frother partitioning in flotationZHANG Wei(张炜)1, 2, Jan E. Nesset2, James A. Finch2(1. Mining & Mineral Resources Division, Department of Business Administration... the adsorption of frother on bubbles and how to influence bubble size is not known. There currently exists no such a topic aiming to link these two key parameters. To fill this vacancy......

Influence of bubble diameter and solids concentration on bubble stability: Development of a novel analytical approachLIU Hong-Jun(刘洪均)1, 2, ZHANG Wei(张炜)2, SUN Chun-Bao(孙春宝)1(1. School of Civil...)Abstract:The properties and thickness of the bubbles in the froth control the flotation process. There is no work showing how to measure bubble film composition and thickness by a straightforward......
Bubble size estimation using interfacial morphological information for mineral flotation process monitoring YANG Chun-hua(阳春华), XU Can-hui(许灿辉), MU Xue-min(牟学民), ZHOU Kai-jun(周开军..., and a binary image containing segmented boundaries was obtained by applying logical rules, thinning and filtering. Statistical features such as bubble size were estimated for control purpose. Experimental......
Effect of some operational variables on bubble size in a pilot-scale mechanical flotation machineZHANG Wei(张炜)1, 2, J.E. Nesset2, J.A. Finch2(1. Mining and Mineral Resources Division, Department...:This work aims to provide a relationship of how the key operational variables of frother type and impeller speed affect the size of bubble (D32). The study was performed using pilot-scale equipment (0.8......
after coalescence, and spherical again after division. These phenomena are explained theoretically. And the bubble size is defined newly. The so-defined bubble size is measured through digital camera and LECO graphical analyzer. And the measured results are compared with those in literatures. Key words: bubble formation; bubble coalescence; bubble division; high-speed digital camera; bubble size......
