Mineral Flotation International Mining

2011-11-1  Flotation has been at the heart of the mineral processing industry for over 100 years, addressing the ‘sulphide’ problem of the early 1900s, and continues to provide one of the most important tools in mineral separation today. The realisation of the effect of a minerals hydrophobicity on flotation all those years ago has allowed us to treat oxides, sulphides and carbonates, coals and industrial minerals economically, and will continue to do so in the future. There have been a number of important changes in the industry over the years as flotation

Evaluation of flotation circuits design using a novel

2020-11-1  The new flotation bank simulator allows for the calculation of the metallurgical behaviour of each cell along a flotation row in terms of the operating conditions, flotation cell design and feed mineral characteristics (Yianatos et al., 2020). The flotation simulator considers the sequential calculation of each single cell in series, assuming a two-zone system: collection and froth (Finch and Dobby, 1990, Yianatos et al., 2008b). This allows the simulator to evaluate different cells size and arrangement in a flotation

Minerals Free Full-Text A Review of Flotation Physical

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the froth must travel increases with an increase in the
