This research, the first step in a program to establish the mechanism of coal flotation, was undertaken to determine the flotation differences of anthracite constituents and thus determine the feasibility of making a constituent separation. Flotation properties were determined by electrical methods. In addition, chemical and physical analyses of the constituents were made to establish some parameters for their differentiation. A constituent classification system is presented. Electrical determinations made on four anthracites and twelve constituents were obtained. The results provide evidence of a difference in adsorption characteristics of the anthracite constituents, indicating the feasibility of making a constituent separation by froth flotation. It was suggested that the relative flotation rates of the anthracite constituents were pH dependent, and that the maximum flotation rate of anthracite occurs in an acidic circuit. The analyses of the anthracite constituents by chemical and physical methods indicated a general correlation with bituminous coal results.
