The influence of the pulp density and the consumption of collection agent, frothing agent, and air on the flotation of coal fines at OAO MMK-Ugol is studied by means of a factorial experiment. First-order regression equations are derived. The response functions selected are the extraction of flammable mass in the concentrate; and the selectivity of the process, includes miscellaneous flotation characteristics. These equations permit the prediction of flotation outcomes.
