Abstract :
This paper describes an online system for froth images of a flotation cellar in mineral processing. The aim of the system setup is to obtain optical information of froth images. Information will then be used for optimization of mineral flotation procedures. In this study, we have designed an illumination system for grabbing froth image with a constant illumination, studied image quality evaluation and classification algorithms. They are used for selecting right types of images for further processing. Special segmentation algorithms for bubbles, and about 40 parameters for froth image analysis are presented. Both DOS software and Windows software have been developed and tested
