  • Froth Flotation Metallurgist Mineral Processing

      A runaway is a frightening experience for a novice flotation operator Froth begins to flow from the surface of the cells at such a rate that launder water sprays cannot break down the froth and it then begins to overflow the launder depositing on the sump floor Even by dropping the cell level, the froth continues to flow and cannot be stopped
