Methods of Improving Mineral Flotation Circuit Performance

Most flotation theory and associated laboratory data have been based on studies where particle size is not a strictly controlled variable. Yet, like the R/K reagent dosage trade-off, lack of knowledge on the interaction of particle size with chemistry and/or equipment can lead to misleading or incorrect conclusions with many single factor tests, e.g. Klimpel and Hansen (1987a, 1988).
