The diagram below illustrates the graphical representation of the unit for a single Primary Metal and Isotherm using the McCabe-Theil method for a single Solvent Extraction stage. Primary Metal in the example is extracted to the Organic Phase.

|For example:
The following is used in [[Solvent Extraction Unit#EXAMPLE 1: Based on total Cu concentration by phase|example 1]], based on 100% stage efficiency.
# Feed Cu(aq) = 1.7 g/L (green vertical line)
# Feed Cu(o) = 2.96 g/L (green horizontal line)
# The operating line's slope = feed stream volume ratio,<br> the operation line y-intercept solved by SysCAD (blue line) 
# To read the equilibrium values:
#*Start from feed Cu(aq), 1.7 g/L, 
#*move vertically up to the operating line
#*then horizontally to the Equilibrium line (magenta Line).
#*exiting Aqueous stream: Cu(aq) = 0.40 g/L
#*exiting Organic stream: Cu(o) = 5.01 g/L

Note the answers obtained for the exiting aqueous and organic streams are the same as obtained using a simple mass balance approach as described in [[Solvent Extraction Unit#Model Theory|Model Theory]].
