Global sensitivity analysis of a mineral processing flowsheet

Performance Profiles for Benchmarking of Global Sensitivity Analysis Algorithms

“…Gan et al (2014) compared various SA methods using a simple conceptual hydrological model. While Sepulveda et al (2013) used the Sobol-Jansen and Morris methods to improve mineral concentration plants. The model used by these authors was the global recovery of the plant, and the results indicated similarity in the results obtained with both methods.…”

Retrofitting of Concentration Plants Using Global Sensitivity Analysis

“…These methods allow the simultaneous exploration of the data space with uncertainty, which is usually performed via Monte Carlo sampling. Sepulveda et al, (2013) applied global sensitivity analysis to analyze separation circuits. The computational cost in terms of simulation models to estimate the sensitivity of higher-order interactions between the inputs can be very high.…”

Global sensitivity analysis for identifying critical process design decisions

“…They derived explicit equations to identify critical stages in mineral concentrators. Sepúlveda et al (2013) extended the previous work, applying global sensitivity analysis to identify critical stages in flotation circuits. They conclude that the method of Sobol' delivers optimal results in the analysis of such circuits.…”
