<i>Moringa oleifera</i> (IMAGE) Uppsala University Caption Previous studies have shown that the extracts from seeds of the Moringa oleifera tree can be used for water purification. In a new study, researchers from Uppsala University show that the Moringa seeds can also be used for separation of different materials. Separation processes are very important in mining industries and the new knowledge could contribute to reduce the needs for expensive synthetic chemicals.
