A METHOD FOR THE PRECIPITATION OF SILICA IN CONNECTION WITH ZINC ORE LEACHING |
| 摘要 |
<p>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 precipitated as silica.</p> |
