This article substantiates the expediency of improving the fluxing ability of limestone and describes new methods for increasing fluxing activity when limestone is being prepared for sintering at crushing-sorting plants. It is shown that sinter plants can pre-clean the limestone by drying it with hot waste gases from under the sintering-machine grates and that it can then be re-cleaned by friction concentration. Results are presented from studies of the effect of the fluxing activity of limestone on the unit productivity of sintering machines and the strength of the sinter.
