This article describes the Reid-Plitt expression for the recovery of classifier feed to underflow, independently reported by Reid (1971) and Plitt (1971).[1][2]

Model theory

Nuvola apps important blue.svg.png This content is available to registered users. Please log in to view.

Excel

The Reid-Plitt efficiency curve model may be invoked from the Excel formula bar with the following function call: 

=mdPartition_ReidPlitt(MeanSize as Range, d50c as Double, m as double, Rf as Double)

Invoking the function with no arguments will print Help text associated with the model, including a link to this page.

The input parameters and model results are defined below in matrix notation, along with an example image showing the selection of the same cells in the Excel interface:
