Graderecovery curves. Graderecovery curves are useful tools in weighing the tradeoff of producing a high grade of concentrate while maintaining as low of a recovery rate as possible, two important aspects of froth flotation. These curves are developed empirically based on the individual froth flotation process of a particular plant.

The existence of such maxima combined with the observed shape of cumulative graderecovery curves leads us to postulate that these curves can be well described by rectangular hyperbolae. Rectangular hyperbolae are characterized by asymptotes at right angles to each other.

How to Make a Bell Curve in Excel (Stepbystep Guide)

Using Individual Growth Curve Models to Predict Recovery

We found evidence of a ceiling effect for the AIS grade D group on the transfer subscore, whose average level of function reached 100 points at about 35 weeks (see fig 3). The 13 and 11item motor subscores are more suitable for modeling AIS grade D recovery, because they include the more difficult items of walking and stairs.
