If insufficient recovery is achieved in the primary vessel rougher flotation scavenger cells may be used. In general all stages do have a common separation goal. For example silica impurity is floated away from hematite in a four stage iron ore circuit in Figure 4. This circuit or variations of it is common when the valuable product is hydrophilic or an underflow product of the column.
