From Introduction: "Vocalization in retorts has been, until recently, the only commercial process of producing spelter, hence the zinc mine operators have had to meet the terms of the zinc mine operators have had to meet the terms of the zinc smelters in regard to the following requirements: (1) Minimum percentage of zinc the ore must contain; (2) the chemical combination of the zinc .
A novel hydrometallurgical procedure is described for the recovery of zinc from zinc silicate ores which have high acid-soluble zinc and silica contents. The process is conducted in a continuous concurrent manner at atmospheric pressure and temperatures of 50 to 95°C. The ore is leached with spent electrolyte from an electrolytic zinc plant to a final pH of approximately 2 to dissolve zinc ...

Abstract A low-grade zinc oxide ore with high silicon was cured by sulfuric acid in a water-starved system and then leached in water. Thermodynamics of the curing process was analyzed according to the phase stability diagram for the systems of Zn-S-O-H and Si-O-H. It was indicated that the extraction of zinc and the dissolution of silica were influenced by the water content in samples during ...
