Solid-solid separations utilizing alkanol amines |
摘要 |
The separation of silica or siliceous gangue from one or more desired minerals in an aqueous slurry via mechanic means is improved by the addition of a small amount of an alkanol amine to the slurry. Examples of separation techniques benefiting from this technology include using cyclones, tables and spiral separators. |
