high silica content zinc ore

Recovery of zinc from a low-grade zinc oxide ore with high

Dec 01, 2016· The low-grade zinc oxide ore with high silica was treated through the process of sulfuric acid curing and water leaching. The ore was firstly cured for 3 h by sulfuric acid with a concentration of 55.17%H 2 SO 4 and a consumption of 1288 kg/t, and then leached using water for 3 h at 50 °C with a liquid to solid ratio of 5:1 mL/g and a stirring

The hydrometallurgical treatment of zinc silicate ores

Mar 01, 1977· 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

WO2002072896A1 A method for the precipitation of silica

The invention relates to a method for the leaching of oxidized ores and in particular zinc ores. The ore, wherein the valuable metals are at least partially in silicate form, are routed to an acidic leaching stage in conditions where the silicate decomposes and the valuable metal ion comes into the solution. During leaching the silicate ion first dissolves, but simultaneously decomposes and is
