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

  2013725 · 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.
