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......

> Abstract: The aggregating behavior between bubbles and particles induced by high intensity conditioning (HIC) was studied using high speed CCD technique. Bubble size measurement... air bubble in flotation cell than those created by normal conditioning. Key words: fine particle flotation; high intensity conditioning; particle aggregation; bubble size measurement
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......
