Predict recovery of single ore source from previous blend and total recovery (2 replies)

I am looking for methods to predict the recovery of a single ore source from historical data, namely a blend of multiple ores in different ratios and overall recovery for each day. It's a CIL plant and the ore types are all similiar in composition and grade.

You could probably play games with multiple simultaneous equations, set up the equations as %x*x_recovery+%y*y_recovery+%z*z_recovery...+%n*n_recovery = overall_recovery, let x = ore source 1, y = ore source 2 etc and solve for the source you want. Hopefully you have enough data to be able to set up these so that they can be solved.

That said - the synergistic effect of the ore types may mess with this approach, and you may not be able to isolate the recovery effectively - but it will be a start.

As noted by Colette, the synergies between different ores in a blend are really important and make it impossible to precisely determine a specific recovery from a particular ore. If you have good data for something like a year, you could certainly run a regression on Minitab or some other statistical program but your R-squared values would be unlikely to be better than 0.5 - 0.6 and might not be that good.
