Prediction of Iron Ore Sinter Strength Using Statistical Technique
The regression value of the model is highly fitted to the actual value (regression coefficient is 0.803), which indicates that the model has good prediction potential for sinter strength. The developed model can act as a tool for prediction of tumbler index, well in advance, which will greatly facilitate the optimization of sinter strength.
