The Peace River iron ore deposit represents the sole source of raw material for an integrated steel industry in Alberta. The ore has proved refractory to beneficiation by a number of techniques. A selective oil-phase agglomeration technique is described. Medium-grade concentrates, analyzing 48-53% Fe and 10-H% SiO2. were obtained with recoveries of about 75% of the total iron. These results appear to represent the optimum possible for this orebody.
