The processing of zinc silicate ores— A review

Previous processes, both pyrometallurgical and hydrometallurgical, for treating zinc silicate ores are reviewed. Some comparisons are made with the new continuous leaching process recently developed by the Electrolytic Zinc Company of Australasia Limited.

Hemimorphite Ores: A Review of Processing

2016-8-24  Most of the above processes for extraction of zinc from hemimorphite ores are carried out in high-temperature blast furnaces or Waelz-type kilns.33 These pyrometallurgical processes can treat high-grade ores, but it may be inappropriate for low-grade zinc-containing hemimorphite ores because of the high capital investment.2

Review of the hydrometallurgical processing of non

2014-10-1  The conventional process of zinc recovery from sulfide ores involves concentrating the low-grade ores by the flotation technique, roasting the concentrate to form zinc oxide, leaching of the resultant calcine with dilute sulfuric acid, followed by electro deposition of zinc from purified leach solution, i.e., the roasting, leaching, electrowinning process.

Selective Recovery of Zinc from Metallurgical Waste

2019-6-19  Zinc sulfide ores or their concentrates are the major primary sources of zinc [1]. Processing of these sources results in the production of residues containing metallurgical slags which are frequently stored in waste piles or landfills. From a chemical point of view, these waste materials are rather complex compositions of oxides, sulfides, carbonates and silicates of metals, whose approximate percentages by weight are within the following ranges: iron—15% to 28%, zinc
