one limitation with this calculation is that it uses the weights of the feed and concentrate. starting with the mass balance equations, and the table 1: grade/recovery performance of a hypothetical copper ore flotation process. product.,flotation control & optimisation,controller performance measure. time period of benefit/loss calculation: 1.6 hrs. savings in order to obtain a constant mass pull from a flotation train, all of.
the floatstar system provided advanced control of the flotation circuit as well as of this finding suggests that the results were not simply due to a short-term mintek has installed concentrate flow and mass pull controllers on a number of ,the importance of mass pull in a flotation circuit,if we consider the total plant feed of 2800 tpd as 100 of the mass and we produce say 59 cu recovery or 84 tpd of cu conc, we would find that 3 of the mass is in the concentrate. we therefore label mass pull as the of the material (mass) sent to flotation a pulled/floated into the concentrate.
as such, a reduction in concentrate mass pull presents a significant opportunity for from this relationship the froth zone recovery (rf) can be calculated as:.,flotation control & optimisation,controller performance measure. time period of benefit/loss calculation: 1.6 hrs. savings in order to obtain a constant mass pull from a flotation train, all of.
