A method for precipitation of silica in connection with zinc ore leaching
本发明涉及氧化矿特别是锌矿浸出的方法。矿石中的有价值金属至少部分是硅酸盐形式的，矿石经历酸性浸出阶段，在该条件下硅酸盐分解，且有价值金属离子进入溶液中。在浸出过程中，硅酸根离子先溶解，但同时分解并作为二氧化硅沉淀。 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...

| Zusammenfassung: | 本发明涉及氧化矿特别是锌矿浸出的方法。矿石中的有价值金属至少部分是硅酸盐形式的，矿石经历酸性浸出阶段，在该条件下硅酸盐分解，且有价值金属离子进入溶液中。在浸出过程中，硅酸根离子先溶解，但同时分解并作为二氧化硅沉淀。
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. |
