Modelling flotation per size liberation class - Part 1 - Minimizing the propagation of experimental errors in the estimate of flotation recovery

This is the first of a series of papers that aims at investigating and modelling flotation per size liberation classes. In this work, the beta adjustment method is detailed and optimized. Results from tests performed on a continuous chalcopyrite flotation circuit shows that the method provides the basis for a consistent balance, allowing to evaluate the flotation performance considering the size liberation classes.
