Froth flotation is an important mineral concentration technique. Faulty conditions in processes may cause the huge waste of resources and reagents, consequently, lead to deterioration terms benefits plants. In this paper, we propose a computer vision-aided fault detection diagnosis approach for froth flotation. Specifically, joint Gabor texture feature based on Copula model designed describe im...

Froth image analysis has been considered widely in the identification of operational regimes flotation circuits, characterisation froths terms bubble size distributions, froth stability and local velocity patterns, or as a basis for development inferential online sensors chemical species froth. Relatively few studies have unsupervised process monitoring applications. In this study, it is shown ...

Froth flotation is the most widely used method of separating minerals from one another. The basis of this process is to control the hydrophobicity of the minerals to be separated. The most commonly used measure of hydrophobicity is the water contact angle (θ), which is usually measured on polished mineral surfaces using either sessile drop or captive bubble technique. However, contact angle is ...
