Abstract:The industrial application of the goethite process has been restricted due to the low recovery of zinc and the great loss of lead and silver in zinc calcine with iron residues. In this study, we examined the properties of +35 mu mzinc calcine and assessed its feasibility for serving as a neutralizing agent in the goethite process. Due to an insoluble fragment or porous structure, the particle size of +35 mu m zinc calcine only decreased slightly at pH 2-3 and 80-90 degrees C. Large differences between iron precipitate and leach residues in the particle size and specific gravity favored the sep
