out of sulfur concentrate. Sulfur concentrate is produced as residue in the flotation of zinc
industry, coming from the leaching process of zinc concentrate. Up to 86.7% of sulfur is
recovered using toluene at 100° C, and a 96.3% of high purity sulfur recovered at room
temperature using carbon disulfide as solvent. The X-ray diffraction of the obtained sulfur is
very similar to the commercial sulfur, and the diffraction data of the residue show no peak of …
