Froth Flotation Circuit Design And Basic Testwork ...

Most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage of flotation. The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5-15 weight percent of the ore feed, (directly related to ore grade).
