The effects of lime addition, temperature, and time on the digestion performance of bauxite and the digestion rate of sulfur were studied. Under the test conditions, with the increase of lime addition and the prolongation of digestion time, the digestion rate of sulfur in the concentrate increases, and the digestion temperature has little effect on the digestion rate of sulfur.
