The Importance of %Mass Pull in a Flotation Circuit | What is Flotation …

Any stage of selective flotation, such as a rougher, must significantly upgrade metal. For example, if a rougher circuit is feed 1% Cu, the concentrate produced by that rougher stage and its reagents needs to be an order of magnitude superior to 2X its feed grade. In this case (1% Cu) a rougher conc greater to 2% Cu should be produced.

Flotation Flowsheets: Key Types and Benefits

A flotation flowsheet should be as simple and flexible as possible, because changes in the ore often necessitate changes in treatment: the more flexible the flotation machine, the easier and quicker the changes can be made, not only in regard to flexibility in arrangement of cells, but also the ability to treat coarse as well as fine material. The flexible points of a "Sub-A" …
