The improvement of an evaporation condensation method allows for successful recovery of elemental sulfur from sulfide concentrates from the zinc industry. Elemental sulfur can be obtained with this method in samples with a low (60%) sulfur content. The effects of heating temperature between 150 degrees C and 250 degrees C and heating time up to 120 min on the recovery of sulfur are also studied. Elemental sulfur obtained in. this way is of high purity and therefore, there is no need for further purification. The treatment of these industrial residues would help removing sulfur from the environment. (C) 2017 Elsevier B.V. All rights reserved.
