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

Dec 01, 2016A low-grade zinc oxide ore with a high of silica was cured by sulfuric acid. • The phase equilibrium diagram for the systems Zn-S-O-H and Si-O-H was derived. • Hemimorphite could be transformed into zinc sulfate monohydrate and silica. • Zinc recovery was 99.22% and the silicic gel could be effectively avoided.

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
