cumulative recovery in flotation benb-bennekom

Flotation kinetic fitting results of cumulative copper recovery of various size fractions as a function of flotation time are shown in Fig. 5 and Table 6. The maximum recovery ( R ∞ ) increased gradually from model 1 to model 6, while the R ∞ values of models 3–5 are basically equivalent.

Timed Flotation Test & Cumulative Grade Recovery Curve

Apart from conducting a rate test in the correct manner, it’s important to collect the right number of concentrates and at the right times; doing this will ensure that the data you generate maximizes your analysis of flotation response. To properly define the relationship between recovery and time, you need a minimum of four concentrates and four data points on the graph. The timing of these

Kinetics of flotation. Order of process, rate constant

Since the cumulative recovery of a component in the concentrate is proportional to flotation time, the flotation process can be considered as a time-rate recovery process. Therefore, a mathematical flotation model that incorporates both the recovery and rate function can completely describe flotation time-recovery profiles.

Laboratory Flotation Testing An Essential Tool for Ore

a function of time, usually on a cumulative basis. A typical cumulative mineral recovery curve is depicted on Figure 2. As an aside, the water in the concentrate versus the water in the flotation cell will be used to estimate recovery by the entrainment mechanism. Thus known quantities (or no) water should be used to wash concentrate into the tray.

Rating Cumulative Grade Recovery Curve Data

Cumulative grade cumulative recovery curves . A plot of the cumulative grade down the banks in a row of flotation cells versus the cumulative recovery often shows a characteristic shape that resembles the shape of a hyperbola. The cumulative grade drops sharply as the cumulative recovery increases to what appears to be a limit. Conversely when the
